You should clarify what exactly people want to say.
You can gather information from Google and create a manual from it; you can even use the structure of questions from the "Physic" guide as a starting point, and then add the nuances of the fourth game later. But this requires someone who has the time and desire to do this painstaking work. The resulting alpha version should be provided to several experts for review, and then to the general public (in case they have any more suggestions). After making corrections, you'll have a fan-made guide. The question is about finding that person. Personally, like most people, I'm willing to play the role of the general public (unfortunately, I don't have what it takes to be an expert).

So, what's the hold-up? Go for it; this is a great opportunity. And you can also participate in tournaments, write walkthroughs, etc.:)

It's better not to browse anywhere else, but to stay on your own portal:mad:
