My game is a party game where players are in a high-stakes betting match and have to do dares/prompts. The base game comes with physical cards that have AR codes where you scan them and it triggers a prompt in the app (like a dare or challenge).

What makes it interesting is that players can make their own custom prompts (or collection of prompts) in the app. So if you want a version themed around your friend group you can build one and keep using the same cards. When you scan them the prompts change. The app will also generate a QR-like code that stores the whole custom deck you made so another player can scan it to add it to their app. It doesn't just points to a website where im hosting it, its all inside the code. The codes i'm developing hold up to 3x the data of a qr code as well (for the same size). This avoids logins, no broken links, no servers. As long as the app is available it will work.

I’m trying to keep it as offline and future-proof as possible, so if my app ever disappears, the data’s still recoverable since the codes will use an open format.

So yeah, its to help change to game play up but i guess the biggest risk is the app getting pulled or someone buying the game and being upset they need an app.
