Flooders Tournament for HoMM III Online

You play the entire tournament with only one castle.

Does that mean you can't capture anything?
Or do you mean with only one race?
I haven't played many tournaments, so I don't know a lot of things.
It seems like there's only one for the 5-player game.
Or 2, I don't remember.

Veg, what's stopping you from installing 3.1? Do you have a limit?
