We played this game on Wednesday night in the hotel in Essen, me demoing it to 3 friends. They all said the buildings were fantastic and really added to the gameplay.
Wait, you carried all this to Essen and back? Just to play it?
I'd be interested in seeing the files for these being released, too.
In the meantime, people could look over here for some good substitutes: Smash Monster Rampage!
