After playing this game by myself, I found it quite interesting in concept but not enough to keep me playing. Once I got one friend over to play I found this game to be a totally new experience. You have to have friends to play this. I wasn't able to test four friends together since due to few people only haveing a GBA. But it was a bawl with two player mode, and I could visualize the competative play during 4 players. I would get this if you know 3 other people with GBA's and is down for a cooperative battle.
