Kenc80 and ezras also feel like trying b4 and it could be good to have a few more games going to figure out bugs faster.
I thought I'd let you host it and let me know if there are any problems with the gamelobby. I'll drop them a private message and join the game as soon as its created. Right now the only official B4 map is a modified version of smallworld (4 players) and a new 1v1 map called ice showdown.
But if you can host it on smallworld or if you have a B3 map and update it to work with B4 (convert in the mapeditor).
Don't make it a team game, it doesnt work 100% yet.
If anyone feel like doing a 1v1 just start a game on a 1v1 map and tell me when both players have joined.
