I was going to give this game 4stars but I just couldn't do it, although there are flaws in the game, I can't bring myself to give it less than 5stars! The 2player co-op mode is fantastic, the way the game has been engineered is truely breath-taking, the graphics, the interaction the 2players can have is just pure fun, but while it is the most fun I have ever had playing a 2player game, on any console, it is also the shortest.
I am hoping that there is a sequel and they only improvement is the length of the game, don't change the game play, don't take this pure brilliance away from us. But give us more of it!
You would be a fool to not own this game!!
