Absolutley brilliant, a little short for my liking, (but i think they could have made it 10 times longer and I'd still have complained) definitley the funniest game I've ever played. There is a co-op mode which would drag out the playtime but I'd need some geek friends and/or a decent internet connection for that. Get it, it's awesome.
