Castlevania Lords of Shadow You won't regret it
Motion is seconded, motion carries. Now carry yourself over to said shop and get that damn game. Best combat-system I've seen, period, and you know what? Great story for once in an action game, and you know what more? It's not short. You heard me, it's an action game with good length to it, for once. And it's so damn pretty.. Now enough talk, have at you!
Edit: And Enslaved, definitely Enslaved.
