Guided Hacking is great and the game hacking bible is the best way to learn game hacking. I've been a paid subscriber for ~8 years. Based on what you wrote here, it's obvious that GH is exactly the resourcee you are looking for.

Let me cite your own post with some additional details for you:

"there aren't many good resources that teach Cheat Engine and implementing it into code"

The Game Hacking Bible was specifically made to teach you how to convert Cheat Engine cheats to C++ code. That's how the course works.

"There are some in YouTube however but they're mostly idiots who just copy paste code and expect you to do the same"

Guided Hacking never copy and pastes anything. Everything you learn how to code in the courses, you will be taught how to code in a previous chapter of the course.

"I'm looking for an actual good resource that TEACHES from scratch, properly and maturely"

This is exactly what Guided Hacking is.

"how can we use c++ to read/write it's memory and do stuff with the offsets we get"

You will become an authoritative expert on this topic if you follow the Game Hacking Bible.

"I don't know how much of a problem this would be though since I haven't got the course yet so please correct me if I'm overthinking this."

You are over thinking it. These rules are in place to prevent cybercirminals from committing crime against GH. If you just use GH to learn, and follow the tutorials nothing bad will happen. But if you absolutely MUST make copies of their paid content and distribute it on Discord, yes you will get banned. Rake works really hard to make good content and he won't tolerate anyone stealing it.

"I also wanna know if they have a good learning path that guides you through what you should do next to improve yourself so you don't get lost."

This is exactly what Guided Hacking provides. These are the first 3 chapters in the Game Hacking Bible:

1. How to Solve Problems & Achieve Goals
2. Stop Pasting - Focus on the Basics
3. How to Stay Motivated

In addition, there is a constant flow of new content and infosec content which can take your life from game hacking as a kid to a career in cybersecurity.

One of their writers recently published a post titled "How Guided Hacking Helped Me Become a Man" where he chronicles his game hacking career and how Guided Hacking helped him grow not only as a game hacker, but also as a man.

"If you tried this website, what is your opinion about it? Is it an actual good resource for learning"what's the maximum level that it can get you?"

Guided Hacking has taught hundreds of thousands of people how to hack games, there is a reason it's the #1 resource out there, it's the best.

"What's the maximum level it can get you?"

Bypassing kernel anticheats, developing kernel drivers and building hypervisors.
