I recently rented Quantum of Solace for the Xbox 360, and my info about the game it sure is fun, but not to own you can beat the campaign in 4-6 hours, the multiplayer part in the game it feels as if it is lacking in certain aspects, I know that the same developer for this game did some work on Call Of Duty World at War, and COD5 was a more complete game the multiplayer is better and more fun if you were thinking on buying this game and renting COD5 I would say buy Call of Duty 5 or World at War.
