"HW rulez" mod (add-on) for HoMM3.

And if, suddenly, a player from this "castrated" environment ends up in a normal one, panic and swearing immediately begin.

I agree with everything else completely, but here, I've heard, it's not quite like that - there are many strong players on Wargame The Red Dragon, some of them probably, like Yog, decided to try something new at some point.

Haven't they come up with the idea of "removing certain units from the starting spawn" yet? Like, no archers - only dwarves and zombies.

Well, why not, I suggested banning ranged attacks a few years ago.
