These days, a lot of games have little re-play value that is why i am in favour of more games having the Karma system.
Games such as Infamous, Fable 2 and Mass effect all have the system and these are the only game I have wanted to go back and play once I have finished so I can experience the game from a different point of view.
IMO if is such a shame that little games have this system, hopefully in the future there will be more!
