On top of being a fantastic party brawler, All-Stars: Battle Royale also happens to be a pretty slick deal if you happen to own both a PS3 and a Vita system. The game includes both versions for the single purchase price and reduced another $20, that's almost stealing. Even if you were just thinking about picking up the Vita version, you should probably grab this two-pack and hand out the PS3 version to a friend.
