Great Single Player Xbox 360 games with good replayability?

I am looking for single player oriented games for the Xbox 360 with good enough replayability and length which can make me play about 5 times before putting it back on the shelf.

I heard Assassin's Creed Brotherhood was a pretty awesome Single player even though it includes Multiplayer now and Dead Rising 2 looks like it has alot of replaybility because of the weapon cominbation.



I dont like Hack and Slash brawlers like Darksiders and I have Fallout 3/New Vegas, Oblivion, and Dragon Age Origins on my PC. I also have Black Ops.Great Single Player Xbox 360 games with good replayability?
I would say Dead Rising 2. Because it's a game that is meant to be replayed.
Borderlands is a great long game with 50 lvls and you are actually required to play through it twice. you will easily get about 50-100hrs of game play.Great Single Player Xbox 360 games with good replayability?
Mass Effect I played that game through prolly 5 times just to see all the permutations of mission order. Also it was awesome In Mass Effect 2 im on 3 playthrough
halo reach online purposes fable 3 is way awesome and fable 2 is way awesome too, mass effect and bio shock are fun as well.Great Single Player Xbox 360 games with good replayability?
