Uncharted is more like an Indiana Jones game than it is a Tomb Raider rip off IMHO. They share similar elements but I don't think they went in there with the intent of "lets make a Tomb Raider game" because Tomb Raider games weren't doing well at all back then. I don't think Tomb Raider going that route is necessarily a bad thing since the PC and Xbox lack Uncharted games, it's a savvy business decision.
