My fav map is the PA countryside. Plenty of wide open space for tanks to cover. Can get into some long range tank battles and maneuver together like real armoured columns do. The sky with the clouds and lightning are pretty sharp too.
I was just thinking that AF might be big right now, just cause its new just as SF was when it came out. 2 weeks later everyone went back to RegBF2. Might be hard to find enough players to start both servers after a week or two.
