With all the rumbling around far far away, this is more than enough to keep you entertained for hours to end...

Very Short
For people expecting a game with a great co-op story mode like Shrek 2 had turn back now! Shrek 3 only has co-op mini games, the main story is single player only.
Besides that the game itself is really short, I knocked it over in a couple of hours today. If you want 1000 quick and easy Achievement points this game is for you, but if you want an involved and well made game, look elsewhere.
I'd recommend this game to kids, or people who are huge fans of Shrek movies. The game feels really rushed and I doubt people that don't fit into one of the above categories will get too much replayability out of it. For $45 I'd recommend you buy a game you won't clear in a day. Shrek 3 will be in the bargain bin soon enough.
