Creating a FизМиГ for HoMM IV.

Exactly, there’s still a lot to do! But this is also important, including magic, creatures, and heroes... Everything is needed. As an example, I suggest reading FizMiGa HoMM 3, created by our forum member, the esteemed AmberSoler... This will give you an idea of what to base your work on. You can find his work at this link: http://homm3world.narod.ru/index.html

By the way, you can also use the same format as there, Excel, as already suggested.
