Creating a FизМиГ for HoMM IV.

I think this "FizMig" should be somewhere in the library section, right?

Not exactly. The library is the library, and "FizMig" is something a bit different. The library showcases the qualitative aspects of the game. :D And "FizMig" focuses on the quantitative aspects. For example, the amount of experience gained in a particular situation, how to best approach that chest (i.e., which side is best to approach it from), how quickly Black Dragons will spawn in Utopia depending on the difficulty, or how a high morale score will affect the damage dealt, and much more! In short, "FizMig" examines the game in greater depth and detail. :)
Consequently, a huge amount of work needs to be done.

If anything, I can help too – within my capabilities – feel free to ask.

Definitely! ;)
