Hmm, let me take a crack at this.
First, the game was originaly written for 4 teams, however, due to anticipated numbers, it was redesigned and released for 2 teams, with a option third if attendance levels mandated it.
Now, as far as Better, I think it will be better with 3 teams fighting over everything, instead of just 2.
Bit to keep things in perspective,, Each village, ( that is if they are smart ) will divide into several squads anyway to go out and deal with the variouse events i have in store for you all.
Remember, Loosing you base costs you, so some people will need to be there at all times.
