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

It's not hard to guess that this contradicts the rules of fair play.

And is using a game bug with water, which gives an unlimited advantage, considered fair play?
I just wanted to say that such loopholes, like "it's not written in the rules, so it's allowed," are simply unscrupulous. A bug is a bug.
Anyway, play HotA. :D
