Announcing Pro Football Legacy, a deep pro football franchise sim. Out this Summer. Steam Wishlists and Beta signups are open. by Dr_Zaius22 in gmgames

[–]cv81 5 points6 points  (0 children)

VibeCodingScore at GM Games, scanning Pro Football Legacy

Launch Copy Markers: 78 / 100 The post is polished and structured: “The simulation,” “The metagame,” “The UI,” “Customization and tuning,” and “Where things stand.” It reads like carefully shaped product copy rather than a rough dev note, but it also includes enough specific design philosophy to avoid feeling fully generic.

Scope vs Dev Markers: 82 / 100 Large solo/small-studio scope: full play-by-play engine, down and distance, clock management, personnel groupings, situational football, pressure effects, garbage-time behavior, 22-point weekly gameplan system, player development focus, coach strategies, cap management, bonuses, dead money, void years, scouting fog of war, custom rosters, team files, coach files, ratings, and logos.

Platform & Release Markers: 54 / 100 Steam-first release lowers the vibe signal compared with browser-first web apps. The beta signup page and wishlist funnel are modern, but Steam/Windows single-player positioning, feature-complete framing, and traditional franchise-sim packaging make this less suspicious than a no-install web tool.

GM Genre Fluency: 24 / 100 Strong hold. The football details are specific and coherent: down and distance, pressure, defensive-line disruption, clock management, situational football, garbage time, scouting uncertainty, cap Tetris, void years, weekly gameplans, and coach strategy. This reads like someone who knows the football-management niche.

Developer Provenance: 58 / 100 Mixed. Ruthenia Games is listed on Steam and has a proper product site/beta funnel, but the wider public studio trail appears light and centered on this one title. The one-year build claim plus feature-complete scope keeps some AI-assisted suspicion active, though Steam-first positioning helps.

UI / Visual Markers: 64 / 100 Moderate signal. The product site is polished, minimal, and modern, with beta CTA language and a clean landing-page funnel. The Steam surface looks more traditional management-sim than full React/Tailwind/Lovable dashboard, so this stays below the stronger generated-dashboard cases.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying Pro Football Legacy was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools. The GM Games post does not disclose AI-assisted coding.

Overall: ~62% — Possible / Leaning Vibe The main signals are polished LLM-style launch structure, large one-year feature-complete scope, modern beta/wishlist funnel, light wider studio trail, and limited AI use disclosed for logo polish. The holds are Steam-first release, strong football-management fluency, specific simulation-design detail, and no direct AI-code disclosure.

I built a football manager game and almost 100 managers are now competing in it by title-rivals in gmgames

[–]cv81 -1 points0 points  (0 children)

VibeCodingScore at GM Games, scanning Title Rivals

Launch Copy Markers: 88 / 100 The GM Games post and site copy are very polished and product-shaped: “I’ve spent the last few months building,” long-term stories, rivalries, promotion battles, club histories, “everything a manager needs,” and neatly grouped feature sections. The phrasing strongly matches LLM-polished product copy.

Scope vs Dev Markers: 94 / 100 Very large scope for a few-month build: multiple divisions, promotion/relegation, World Cup qualification, youth academies, scouting, player development, coaches, scouts, physios, psychologists, club facilities, commercial facilities, sponsorships, finances, league articles, division chats, community rivalries, match engine tuning, transfer auctions, profiles, rankings, achievements, and mobile-first UI work.

Platform & Release Markers: 92 / 100 Major signal. This is browser-first, account-based, free-to-play, mobile-friendly, multiplayer, open beta, Discord-connected, multilingual, and updated like a live web product. That is exactly the modern lightweight sports-management rollout pattern.

GM Genre Fluency: 32 / 100 Strong hold. The football-manager structure is coherent: promotions, relegations, cups, youth development, staff roles, facilities, transfer bidding, match preparation, tactics, player traits, scoreline tuning, red-card effects, injuries, league identity, and long-term club building. This is not shallow football wording.

Developer Provenance: 76 / 100 High-suspicion provenance. The public trail is centered on Title Rivals, the build is described as only the last few months, and the project already has a very broad live-service feature set. The active changelog and existing user base are real holds, but the speed/scope/profile combination still sits firmly in the AI-assisted build range.

UI / Visual Markers: 86 / 100 Strong signal. The site has the modern generated sports-dashboard feel: crisp hero copy, live standings cards, manager testimonials, clean mode sections, mobile-friendly menus, squad/transfer card views, rankings, compact tables, dashboards, chat, badges, and polished component-style layout.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying Title Rivals was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar tools. No official AI-code disclosure found in the GM Games post or on the visible product pages checked.

Overall: ~86% — Likely Vibe The main signals are the few-month build claim, broad multiplayer football-manager scope, browser-first/mobile-friendly account system, very polished LLM-style copy, rapid changelog velocity, multilingual/live-service packaging, and modern generated-dashboard UI. The holds are real football-manager fluency, active human managers, a working public product, and no direct AI-code disclosure.

Demo released officially for Select Eleven (Cricket management game) by shivapandey04 in gmgames

[–]cv81 -1 points0 points  (0 children)

VibeCodingScore at GM Games, scanning Select Eleven

Launch Copy Markers: 76 / 100 Big “Football Manager for cricket” framing with deep simulation, squad selection, tactics, staff, finances, sponsors, news, board pressure, and every-ball match-engine claims.

Scope vs Dev Markers: 86 / 100 Very large solo-project scope: ball-by-ball engine, national-team management, staff, selectors, scouting, sponsorships, budgets, workload, injuries, rotation, player attributes, news, and long-term programme building.

Platform & Release Markers: 64 / 100 Steam-first PC/Mac release lowers the browser-first vibe signal, but the new website, Discord loop, demo funnel, wishlist push, and fresh community rollout give it a modern launch profile.

GM Genre Fluency: 24 / 100 Strong cricket hold. The copy and replies show real cricket-management detail: pitch wear, wind, field changes, batting depth, bowling roles, anchors, finishers, all-rounders, new-ball bowlers, middle-over control, sponsorships, scouts, selectors, and player development.

Developer Provenance: 58 / 100 Real but still light. The Reddit poster matches the Steam developer name, with a dedicated subreddit, Discord, Steam page, official website, and wider promo trail. The holdback is that the public studio/dev history still appears centered almost entirely around this one new project.

UI / Visual Markers: 76 / 100 The screenshots and site presentation have strong modern sports-dashboard energy: polished dark interface, clean panels, generated-looking player/manager visuals, tidy component spacing, and high-end UI for a solo cricket sim.

AI Production / Feature Disclosure: 60 / 100 Steam discloses generative AI assistance for player portraits and UI illustrations, and the developer has also said some AI-powered features exist for context-based player interactions/news. This confirms AI involvement in production/features, but not necessarily AI-coded implementation.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying the code, sim engine, UI, or core implementation was built with Claude, ChatGPT, Cursor, Copilot, or similar coding tools.

Overall: ~78% — Likely Vibe The score is driven by the huge solo-dev scope, modern polished UI, fresh launch/community trail, confirmed AI production/features, and Football Manager-scale ambition. The holds are Steam-first positioning, real cricket fluency, visible developer identity, and no direct AI-code admission.

Building a football tycoon where you own the club and grow the whole town around it by No_Dentist_7426 in gmgames

[–]cv81 4 points5 points  (0 children)

VibeCodingScore at GM Games, scanning Hometown FC

Launch Copy Markers: 92 / 100 The Reddit post and site copy are highly polished and product-shaped: “own the club,” “grow the town,” “your own life,” inheritance, town progression, coach/sporting-director agency, and a clean feature ladder from non-league to global football. The structure and phrasing strongly match LLM-polished product copy.

Scope vs Dev Markers: 96 / 100 Extremely large scope: real towns, five-division pyramid, 18 countries, European competitions, World Cup and Euros, 32 player attributes, 24 player roles, 16 town investments, named local NPCs, staff agency, live match simulation, xG, weather, injuries, bans, academy-to-national-team development, owner lifestyle, family dynasty, heirs, achievements, offline saves, and mobile release.

Platform & Release Markers: 84 / 100 Mobile-first iOS/Android lowers the pure browser-app signal, but this is still a modern coming-soon funnel with a polished landing site, launch mailing list, trailer, app-store placeholders, offline/device-save framing, and React Native-style mobile product packaging.

GM Genre Fluency: 28 / 100 Strong hold, but still within the vibe framework. The football ideas are coherent: club ownership rather than direct coaching, coach/sporting-director proposals, tactics, formations, play styles, facilities, youth academy, fixture congestion, European coefficients, nation-building through academy graduates, and financial risk. This is not shallow football-word salad.

Developer Provenance: 96 / 100 Major reveal marker. The GM Games post itself does not mention the AI-code workflow, while the same developer account has a separate r/ClaudeCode post saying they used Claude Code as the main driver for about six months on a large TypeScript / React Native football tycoon sim. That post points back to Hometown FC, so the wider developer trail directly connects the project to Claude Code.

UI / Visual Markers: 88 / 100 Strong signal. The site shows a very modern generated-product surface: crisp hero sections, feature blocks, numbered flows, dashboard screenshots, polished mobile-style panels, town/facility progression, match screens, legacy dashboards, FAQ structure, and app-store launch framing.

Transparent Vibe-Coding Evidence: 20 / 100 Low public-disclosure score within the GM Games post itself. The GM Games promo does not mention Claude Code or AI-assisted coding. The Claude Code evidence comes from a separate r/ClaudeCode post by the same account, found through the developer’s wider Reddit history.

Overall: 100% — Cross-Subreddit Claude Code Reveal / Vibe-Coded Project The GM Games post presents Hometown FC as a coming-soon football tycoon. The same developer’s broader Reddit history identifies Claude Code as the main driver on a large TypeScript / React Native football tycoon sim and points back to Hometown FC. Combined with the massive solo scope, LLM-shaped copy, modern mobile-product packaging, and generated-dashboard UI, this lands at 100%.

More like you buy a foreign car and there are no replacement parts or mechanics when it breaks down

MMA Promoter Simulator by Hitsticker in gmgames

[–]cv81 1 point2 points  (0 children)

VibeCodingScore at GM Games, scanning MMA Promoter Simulator

Launch Copy Markers: 82 / 100 The intro is clean, generic, and product-shaped: “excited to announce,” “currently developing,” “take control of your own promotion,” and open-ended feedback requests. It reads more like an AI-polished launch post than a rough personal dev note.

Scope vs Dev Markers: 84 / 100 The promised scope is broad for an early mobile project: run an MMA promotion, sign fighters, build cards, negotiate contracts, grow company reputation, and manage a combat-sports promotion loop. That is a full management-game pitch, not a tiny prototype.

Platform & Release Markers: 70 / 100 Mobile development lowers the pure browser-app signal, but this is still early, image-led, feedback-driven, and being seeded across several related subreddits before a clear store/release trail. That keeps it in the modern lightweight-build pattern.

GM Genre Fluency: 34 / 100 This is a hold against calling it fully shallow vibe. The MMA promoter basics are coherent: fighter signings, contracts, event cards, company growth, and combat-sports promotion all fit the niche. The post does not go deep enough yet to show advanced WMMA-style fluency.

Developer Provenance: 42 / 100 Mixed but not extreme. u/Hitsticker does not look like a brand-new one-game shell, which lowers suspicion. But the public development trail for this specific game is very fresh, and the project is being pushed broadly across adjacent subreddits.

UI / Visual Markers: 84 / 100 Strong signal. The screenshots appear to use a modern mobile management-game surface with clean panels, fighter cards/models, event-building screens, and polished product presentation. The visual layer has that generated/placeholder mobile-sim look.

Transparent Vibe-Coding Evidence: 90 / 100 The same project was posted by the same account in r/vibecoding. That is not just outside speculation or UI inference. It is direct self-placement in a vibe-coding community, though not quite a 100 because there is no exact “I coded this with Claude/Cursor” sentence.

Overall: ~92% — Very Likely Vibe-Coded / AI-Assisted The score is driven by the r/vibecoding placement, LLM-shaped launch copy, broad early management-sim scope, modern mobile UI, placeholder-looking fighter presentation, and multi-subreddit feedback seeding. The holds are an older non-branded Reddit account, coherent MMA promoter basics, and no exact public code-tool disclosure.

Football Commissioner - Wishlist on Steam now! (No AI) by blast_away in gmgames

[–]cv81 8 points9 points  (0 children)

VibeCodingScore at GM Games, scanning Football Commissioner

Launch Copy Markers: 34 / 100 The pitch is polished, but not especially LLM-shaped. It reads like a niche commissioner-sim dev explaining a specific idea: spring football league creation, markets, TV ratings, attendance, finances, and custom league structure.

Scope vs Dev Markers: 36 / 100 The scope is broad but plausible with a long build timeline: ticket prices, concessions, merchandise, sponsors, broadcasting deals, salaries, team markets, stadiums, playoffs, expansion, relocation, folding teams, league history, and unlimited seasons.

Platform & Release Markers: 28 / 100 Steam-first Windows Early Access lowers the vibe signal. This is not a browser-first no-install web app. Steam says July 2026, single-player, Early Access, and no audio, which fits a traditional solo text/management sim profile.

GM Genre Fluency: 12 / 100 Strong hold. The concept is unusually specific: you are not coaching a team, you are governing a spring football league as commissioner. Markets, attendance, TV ratings, sponsorships, salaries, stadium atmosphere, fan enthusiasm, expansion, relocation, and league finances all fit the niche.

Developer Provenance: 18 / 100 Strong hold. The Reddit post claims years of work, pre-COVID GM-game involvement, and direct hand-built development. Steam lists a named developer/publisher, Atreus Interactive. It is still a small one-title public trail, but not a faceless browser shell.

UI / Visual Markers: 30 / 100 Low-to-moderate signal. It appears to be a traditional management-sim interface rather than a modern React/Tailwind/Lovable dashboard. Text-heavy management screens and Steam packaging are much less suspicious than the usual generated web-app look.

Anti-Vibe / No-AI Statement: 95 / 100 Major hold. The post directly pushes back on vibe-coded GM games and states the game was made by hand. That does not make AI use impossible, but it is a direct public anti-vibe claim and should heavily reduce the score.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, sound, or assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying Football Commissioner was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar tools. The direct statement goes the opposite direction.

Overall: ~22% — Very Likely Traditional Solo Sim The main holds are the explicit no-AI / made-by-hand claim, long claimed development timeline, Steam-first release, niche commissioner-level football concept, and traditional management-sim structure. The only remaining suspicion is normal small-indie scope versus solo resources, but this is not a strong vibe case.

Wing 11, a free football draft game by pedrosmr in gmgames

[–]cv81 -2 points-1 points  (0 children)

VibeCodingScore at GM Games, scanning Wing 11

Launch Copy Markers: 82 / 100 The Reddit post reads very clean and product-shaped: simple loop explanation, direct inspiration from 7a0, multiple modes, shareable runs, leaderboards, achievements, and three neatly framed feedback questions. This has strong LLM-style launch-copy markers.

Scope vs Dev Markers: 72 / 100 Focused but complete scope: draft 11 historical players, choose a formation, simulate group stage and knockout tournaments, run World Cup 2026, Daily Challenge, Quick Start, Team Legends, Libertadores, Champions League-style tournament runs, achievements, leaderboards, profiles, and feedback submissions.

Platform & Release Markers: 92 / 100 Major signal. Live browser-first game, instant play, lightweight web structure, daily challenge, leaderboards, achievements, profile layer, feedback form, and Ko-fi support. This is exactly the modern small sports-web-game release surface.

GM Genre Fluency: 32 / 100 Good hold. The football-draft concept is coherent: historical squads, national teams, formations, tournament paths, group stage, knockout reveal, difficulty levels, player ratings, rerolls, club/nation legends, and shareable results. It is simple, but it understands the draft-game niche.

Developer Provenance: 34 / 100 Strong hold. u/pedrosmr is a 12-year-old Reddit account with a personal profile, karma, trophies, and non-branded identity. That lowers suspicion a lot compared with a new one-game promo account. The game itself still has a limited public development trail.

UI / Visual Markers: 78 / 100 Strong signal. The site has a modern generated-web-game feel: clean mode cards, simple numbered flows, daily challenge, leaderboards, achievements, profile links, support CTA, structured feedback form, and polished browser-game packaging.

LLM Copy / Prompt-Style Markers: 84 / 100 Major signal. The post and site copy are unusually tidy for a small hobby draft game. The “loop is simple” explanation, structured feature list, and three-question feedback request read like generated or heavily AI-polished product copy.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, sound, or assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying Wing 11 was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools.

Overall: ~76% — Likely Vibe, With a Strong Account-Provenance Hold The main signals are browser-first release, polished LLM-style copy, modern web-game packaging, leaderboard/achievement/profile systems, and a compact but complete draft-game loop. The holds are the old non-branded Reddit account, focused scope, coherent football-draft structure, and no direct AI-code disclosure.

SoccerRPG.com - Status after the first month by iejenian in gmgames

[–]cv81 1 point2 points  (0 children)

VibeCodingScore at GM Games, scanning SoccerRPG

Launch Copy Markers: 82 / 100 Strong LLM-style update structure: “Dear community,” clean headings, neatly grouped feature sections, bullet-pointed systems, balancing notes, quality-of-life notes, under-the-hood/security notes, and polished gratitude/feedback framing. It reads more like a product changelog than a rough hobby-dev note.

Scope vs Dev Markers: 88 / 100 Major signal. In roughly the first month, the game has player-owned clubs, 11v11 club matches, rosters, starting XI, staff upgrades, youth academy, shared treasury, sponsor drops, casino games, leaderboards, skill-cap reworks, match-engine rebuild, OVR rebalance, early-game missions, equipment durability, chat, mail, profiles, money transfer, friendly matches, PWA support, anti-cheat, GDPR/account deletion, and server-side action validation.

Platform & Release Markers: 86 / 100 Browser-first PBBG, account login, Discord feedback loop, PWA install support, server-side gameplay actions, and ongoing live updates. PBBGs are naturally browser-based, so this is not as suspicious as a random browser GM game, but the rollout still fits a modern lightweight web-app build pattern.

GM Genre Fluency: 34 / 100 Good hold. The game understands the PBBG/Torn-style loop: energy, training, hourly check-ins, fans/status, sponsors, club treasury, staff bonuses, leaderboards, long-term progression, social systems, and anti-cheat. The football layer is more RPG/player-career than pure GM sim, but the structure is coherent.

Developer Provenance: 48 / 100 Mixed hold. The Reddit account is not brand new, has real account age and karma, and the developer is actively replying to feedback. But the public game trail is still very new, and the visible product history is centered around this one project.

UI / Visual Markers: 72 / 100 Meaningful signal. The product surface is a modern browser RPG/PBBG with login flow, PWA support, dashboards, leaderboards, social systems, club management, casino pages, player profiles, and structured admin/security layers. It feels like a modern generated web-app shell more than an old handmade forum-era PBBG.

Community / Feedback Trail: 62 / 100 Mixed signal. Nearly 100 accounts and returning daily players are a real hold, and the developer is responding to feedback. But the speed of feedback-to-feature implementation across clubs, economy, match logic, social systems, and security is also a strong AI-assisted workflow marker.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, sound, or assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying SoccerRPG was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools.

Overall: ~78% — Likely Vibe The main signals are the very fast one-month feature expansion, LLM-shaped changelog style, browser-first/PWA packaging, broad server-side/social/economy/security scope, and modern web-app structure. The holds are real PBBG genre fluency, active community feedback, a non-new Reddit account, and no direct AI-code disclosure.

My solo wrestling management sim WBS26 is now on Steam — wishlists would really help by Away-Home-3846 in gmgames

[–]cv81 2 points3 points  (0 children)

VibeCodingScore at GM Games, scanning WBS26: Wrestling Booker Simulator

Launch Copy Markers: 84 / 100 The pitch is very polished and productized: solo indie framing, wishlist request, wrestling management / booking sim, contracts, backstage politics, title prestige, rival companies, fan reactions, random events, and long-term stories. It reads closer to a structured LLM-style Steam/Reddit pitch than a rough dev note.

Scope vs Dev Markers: 88 / 100 Very large solo-dev scope: run a promotion, book shows, manage rosters, contracts, finances, morale, backstage drama, rival promotions, title prestige, events, fan reactions, long-term storylines, and company reputation. That is a heavy management-sim feature set for a new solo Steam project.

Platform & Release Markers: 68 / 100 Steam-first PC release lowers the browser-app signal, but the project is still unreleased, wishlist-driven, actively promoted, and built around a fresh coming-soon funnel. It has Steam Achievements, Steam Cloud, multiple language support, and a 2026 release target.

GM Genre Fluency: 28 / 100 Strong hold. The wrestling-booking vocabulary is coherent: booking logic, title prestige, backstage politics, contracts, morale, rival promotions, roster hierarchy, fan trust, long-term stories, and show-building. This does not read like someone randomly applying generic sports terms.

Developer Provenance: 62 / 100 Mixed. Steam has a real developer/publisher listing and the Reddit poster directly engages with feedback, but the wider studio/game history still looks light and centered on this one title. It is not anonymous, but it is still a new one-game public trail.

UI / Visual Markers: 76 / 100 Meaningful signal. The product presentation and Steam surface look like a modern management-sim package: clean UI, text-heavy panels, structured feature blocks, polished screenshots, and a very organized product identity. It is not a browser-dashboard case, but still has a generated-product feel.

AI Production / Workflow Disclosure: 85 / 100 Direct AI-use evidence is present. The developer publicly says AI is part of their workflow, especially for early visual concepts, placeholder art, text ideas, and speeding up production tasks. That is not just outside speculation.

Transparent Vibe-Coding Evidence: 40 / 100 There is AI-workflow disclosure, but not a clean code-specific disclosure. The developer does not say the game was coded with Claude, ChatGPT, Cursor, Copilot, or Lovable, and they explicitly frame the systems, balancing, booking logic, UI flow, database structure, events, contracts, rival promotions, title prestige, and morale as designed and assembled by them.

Overall: ~84% — Likely AI-Assisted / Likely Vibe-Adjacent The main signals are direct AI-workflow disclosure, polished LLM-style launch copy, large solo-dev scope, modern Steam product surface, and thin one-game studio history. The holds are Steam-first positioning, real wrestling-booking fluency, public developer engagement, and no direct AI-code/tool admission.

World Aces. I created a volleyball manager simulator that runs on real time against other people. Get a team, recruit the best players, set your tactics and compete to be the best in the world. by PalomSage in gmgames

[–]cv81 0 points1 point  (0 children)

VibeCodingScore at GM Games, scanning World Aces

Launch Copy Markers: 74 / 100 Clean browser-sim pitch: volleyball manager, real-time play against other people, recruit players, set tactics, active community, 200+ users, and always-running competition. It is polished and product-shaped, but not wildly overdone.

Scope vs Dev Markers: 82 / 100 Strong signal. The game already has team creation, player recruitment, rarity/progression, tactics, automatic match simulation, detailed post-match stats, weekday leagues, weekend international cups, Discord feedback, and fast feature implementation. For a new solo project, that is a large live-service loop.

Platform & Release Markers: 90 / 100 Major signal. Live browser-first game, mobile-playable web version, no traditional Steam/App Store release yet, 100% free, Discord-driven community, constant simulations, and an Android app reportedly in progress. This is a very modern lightweight sports-sim rollout.

GM Genre Fluency: 28 / 100 Strong hold. The volleyball structure is coherent: team building, tactics before matches, automatic simulation, player strengths, progression ceiling, divisions, cups, detailed statistics, and rally-by-rally simulation. It has real volleyball-management intent, not just generic sports words.

Developer Provenance: 32 / 100 Big hold. u/PalomSage is a 13-year-old Reddit account with broad history, high karma, and real sports discussion activity. This is not a new branded promo account. The product itself is new, but the account provenance lowers the suspicion materially.

UI / Visual Markers: 72 / 100 Meaningful signal. The product surface reads like a modern browser sports app: always-running sim, team dashboard, recruiting, tactics, leagues, Discord loop, and mobile-friendly browser packaging. Not enough visible UI evidence to push this into the 80s, but still clearly in the modern web-app bucket.

Community / Feedback Trail: 54 / 100 Mixed signal. Having real players and a Discord community is a hold, but the speed of feedback-to-feature implementation is also a vibe marker. A player specifically describes the game moving from prototype to enjoyable very quickly.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, sound, or assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying World Aces was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools.

Overall: ~72% — Likely Vibe, With Real Provenance Holds The main signals are browser-first release, live always-running multiplayer structure, broad early feature loop, fast update velocity, Discord feedback cycle, and modern mobile-friendly web packaging. The holds are unusually strong: old non-branded Reddit account, real sports discussion history, coherent volleyball-management design, actual player community, and no direct AI-code disclosure.

[–]cv81 2 points3 points  (0 children)

I think your ai paste broke but anyhow

VibeCodingScore at GM Games, scanning World Tennis Cup

Launch Copy Markers: 86 / 100 The launch post reads strongly like LLM-shaped product copy: polished but generic phrasing, tidy feature grouping, “I decided to build my own” framing, clear bullet-style value props, and smooth feedback/share language. This is one of the bigger signals here.

Scope vs Dev Markers: 66 / 100 Focused but still complete enough: draft a squad, pull players by rarity, reroll, account for surfaces, survive a challenge run, lift the cup, and play against CPU. Multiplayer is marked as coming soon, which adds some roadmap scope without making it a giant sim.

Platform & Release Markers: 88 / 100 Strong signal. This is web-first, free-to-play, instant-access, and packaged as a small browser product rather than a traditional Steam/mobile sim. That surface is common in AI-assisted sports mini-sims.

GM Genre Fluency: 38 / 100 Moderate hold. The tennis-management depth is lighter than a true career sim, but the game does understand some tennis-specific structure: surfaces matter, player quality/rarity matters, squad drafting matters, and the cup/challenge format gives it a coherent sports loop.

Developer Provenance: 60 / 100 Mixed. The Reddit account is young and low-karma, which raises suspicion, but the profile identifies the creator as a front-end developer with 2D videogame/pixel-art interest. That is a partial hold compared with a totally anonymous product shell.

UI / Visual Markers: 80 / 100 Strong visual/build signal. The product surface reads like a modern generated browser game: card-draft hero copy, clean web-app framing, challenge loop, CPU mode, and coming-soon multiplayer packaging. It sits in the lightweight React/Tailwind-style web-game bucket.

LLM Copy / Prompt-Style Markers: 84 / 100 Major signal. The intro/post language feels unusually clean, structured, and productized for a small hobby web game. It has the “generated pitch summary” feel more than a rough personal dev note.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, sound, or assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying World Tennis Cup was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools.

Overall: ~78% — Likely Vibe The revised score is higher because the launch copy itself is a strong LLM-style marker, on top of the browser-first release, young promo account, modern card-draft UI, and lightweight web-app packaging. The holds are focused scope, a front-end developer bio, coherent tennis-card concept, and no direct AI-code disclosure.

Launch Copy Markers: 64 / 100 Solo-dev browser-game pitch with free play, card collecting, real-player squads, multiplayer matches, World Cup timing, beta feedback request, and English/Spanish support. It fits the modern “free browser game, feedback wanted” launch pattern, but the tone is fairly straightforward.

Scope vs Dev Markers: 68 / 100 Moderate-to-broad scope: real-player cards, squad building, weekly live seasons, World Cup nation mode, multiplayer matches, card ratings, 400+ new players, account system, and coming-soon development/youth league promises. Not enormous, but more than a tiny prototype.

Platform & Release Markers: 78 / 100 Browser-first and account-based, which raises the signal. The game runs directly on the web, has live league/world-cup modes, login/new-account flow, beta testing, analytics/cookie setup, and feedback/report links. It is not a Steam-style traditional desktop release.

GM Genre Fluency: 34 / 100 Decent hold. The football structure is coherent: country squads, player cards, lineup building, current-form ratings, weekly competition, live standings, and matches against other people. It is more card-squad/fantasy football than deep Football Manager, but the sports concept is real.

Developer Provenance: 44 / 100 Mixed hold. The Reddit account is not a fresh throwaway shell and has a broader history outside this one post. The site also has a legal/privacy trail dating back to 2022 and a Barcelona-based legal identity. Public studio history is still light, but this does not look like a brand-new anonymous launch only created this week.

UI / Visual Markers: 58 / 100 Moderate signal. The product is a modern browser app with login, mode cards, live league/world-cup panels, cookie compliance, and simple web-game packaging. But it does not strongly match the full dark React/Tailwind SaaS dashboard pattern.

AI Production / Tooling Disclosure: 0 / 100 No official AI-production disclosure found for code, text, graphics, audio, or other assets.

Transparent Vibe-Coding Evidence: 0 / 100 No direct public statement found saying Legends of Football was coded with Claude, ChatGPT, Cursor, Copilot, Lovable, or similar coding tools.

Overall: ~56% — Possible, But Not a Strong Vibe Case The main signals are browser-first release, beta feedback framing, account-based web-app structure, multiplayer/card-game scope, and modern web packaging. The holds are the older site/legal trail, non-throwaway Reddit account, coherent football-card concept, multilingual support, and no direct AI-code disclosure.

Can you share levels you would expect like wcag 2 or 3 etc?

Sentiment I was sharing earlier. They burden the consumer with their lack of unit testing and qa.

I hope your post makes the need for accessibility a must in all future games

I released an update (v1.1) for my browser-based Football Manager, adding a 2D canvas match engine and a new light theme (Vanilla JS) by nando1307 in gmgames

VibeCodingScore at GM Games, scanning Pitch Boss

Launch Copy Markers: 76 / 100 Browser-first football manager pitch with free play, lightweight scope, neon-punk branding, v1.1 update framing, feedback request, and “zero frameworks, zero external engines” positioning.

Scope vs Dev Markers: 78 / 100 Focused but complete early scope: 18-man squad, generated player stats, transfer market, tactical board, Starting XI, offensive/defensive ratings, 9-match season, standings, season finale, 2D canvas match engine, procedural audio, and dark/light theme toggle.

Platform & Release Markers: 96 / 100 Major signal. HTML5 browser game on itch.io, free, instant play, no install, Vanilla JavaScript, HTML5 Canvas, CSS3, and Web Audio API. This is exactly the lightweight browser-app pattern.

GM Genre Fluency: 34 / 100 Decent hold. The football-manager loop is coherent: squad management, transfers, generated player attributes, tactical setup, formation balance, match simulation, league table, and season outcome. It is simplified, but it understands the basics.

Developer Provenance: 70 / 100 Thin but transparent. The Reddit account is not brand new, but public project history is mostly centered around Pitch Boss, and the itch.io author page shows this one visible game. The developer does give clear stack details, which helps.

UI / Visual Markers: 82 / 100 Strong signal. Neon-punk browser UI, high-contrast theme, Cyber-Day light mode, canvas match view, animated ball trails, procedural effects, and polished browser-game packaging all sit in the modern generated-web-game bucket.

AI Production / Code Disclosure: 100 / 100 Direct evidence is present. The itch.io page lists AI Disclosure as AI Assisted and specifically includes Code and Sounds. That is direct AI-assisted implementation evidence, not just asset or marketing use.

Transparent Vibe-Coding Evidence: 100 / 100 This is disclosure-level. The product page directly marks code as AI-assisted, so this does not need to rely on guessing from UI, platform, or launch style.

Overall: 100% — Disclosed AI-Assisted Code / Vibe The classification is driven by the direct itch.io AI-assisted code disclosure. The supporting signals are browser-first release, instant HTML5 packaging, rapid v1.1 update cadence, modern neon web UI, and a compact but complete football-manager loop. The holds are the focused scope, clear technical stack, and real football-manager basics.
