I recently got Uncharted 2 and I beat it and it doesn't have much of a replay value so I would like to return it while I still can. (Game Stop's return a used game within a week deal). And I'm trying to decide wether I should keep it, or get Infamous, or get Little Big Planet, or get Assassin's Creed 2. I would like to have a headset for Little Big Planet and I don't have one yet, but what do you guys think?
EDIT: Not getting AC2. My friend just got it and I'm going to borrow it from him when he's done with it.
