Uhh..GOW2 is sick. I've been playing for days now, and I haven't gotten bored. Playing the Horde mode is a lot of fun, and when you get to the higher waves, it's insane! The maps are really cool, and the story mode kicks ass. Coop on the campaign is also a lot of fun, and while it can be beat in a relatively short period of time, the multiplayer stuff will keep you going for endless. It's a must have for sure!
