Could map size be x-large? or vote, or agreement between opponents, or something? Smaller maps require a better knowledge of game mechanics, while larger maps require better knowledge of war making. Therefore smaller maps favor players more experienced in the game, while larger maps diminish that advantage.
Also how do you determine who creates, and hence who goes first?
Even if the creator of the game is honest, it flashes a snapshot of the map, "shroud on" will let creator peak, this might not be fair. I raise these questions only for clarity, I will play anyway.
Man I can't freakin wait!
