i havent taken a good look at the map selection but some of them were large enough that you could just run people around if they had the hammer or were invincible whatever. one of the guys in the IGN podcast tried to explain that a person losing would have a much easier chance of breaking the smash ball then a person winning. since its most likely not a part of SSE which they were trying to make the game more single player friendly it seems kind of thrown in there.
