Flooders Tournament for HoMM III Online

I've always wanted to play the original Back For Revenge and A Viking We Shall Go, but these maps imply a long game.

Back For Revenge is very good; I wouldn't mind playing it... but unfortunately, much of it is tied to navigation, so even in single-player, the game takes a couple of months... brr
I wouldn't refuse to play Jebus with four people if there's time.
