Nameless Hero
Auto-translated
I don't see any "overload" in the fact that each creature has unique (or almost unique) active and passive abilities. This actually deepens and expands the gameplay. It's definitely better than the mindless creatures in Heroes 7 and the original Heroes 2 (though, of course, people would criticize the 1996 game now). Where the creatures differ only in their visuals and stats. And we shouldn't cater to casual gamers when making a game in the HoMM series. There are plenty of games for them already...
