We can have more than one game going at a time too, with different people, so if you're waiting for someone to make a turn, who isn't even there, you could have like three other games going too. Maps can be up to 40 x 40 in the map maker, and can have up to 14 teams. The only thing that sucks about making a big map though, is that you can't click and drag, and you have to click one square at a time as far as I know at least.
My username is Shaylle, and I have a game going already. PM or IM me for the password if you want to join. So far it's just Scott and me and we need two more players.
