I WOULD NOT recommend buying this game. Rent it! You can beat it in less than 6 hours and an EASY 800+ achievement pts
From a game standpoint, you play as a character who is not on the show. As for the gameplay, it's very linear and very easy. The reason I am glad I rented this is cause it took me maybe 5 hours and I beat the game - and in doing so, I unlocked 835 achievement points. If I get a whild hair up my behind, I may go through it again just to take pictures of stuff (10 secret achievements I missed) that I missed going through the game.
All in all, if you're a fan of the show - eh, MAYBE this is a renter if you're looking for 5 hours to kill and want an easy 800+ achievement points. As far as buying it, DONT!! The replay value is simply not there. Spend the $6 renting it as opposed to wasting $30 buying it. You'll get a little enjoyment out of the game and will be pleased that you dind't waste money buying this.
If you're not a fan of the show, I don't know that I'd even rent this for it's not that great of a game, and it's pretty basic and very linear. The story will seem VERY choppy and unclear as a lot of the stuff in the game gets skipped as it's explained in the actual show. It's assumed that you know what's going on.
