What game should I buy for Xbox 360?

I already have L4D2, Assassins creed 2, Cod Modern Warfare 2 and dragon age, but I would like some ideas of what game to spend my last 拢40 on. best suggestion = top points.What game should I buy for Xbox 360?
I think you should get one of these. Borderlands is an rpg and fps combination game. You get the most bang for your buck here. There is also Halo 3 Odst, the second best fps behind MW2. Prototype you are infected by a virus which gives u power to become a hero. Forza Motorsport 3 if you like racing. Best suggestion would be Borderlands you have Dragon Age Origins and MW2 you should like it. Hope I helped you out.
Borderlands. Really fun game, albeit a short story line. Absolutely worth the money tho, and the DLC (so far) is pretty sweet too.What game should I buy for Xbox 360?
I'm playing The Sabatour at the moment and it's fab. A cross between GTA and Assasins Creed but I think better than those two. If you want an old game get Oblivion as it is massive and take you ages to complete all of it.
I'm not from the UK idk how monopoly money works but if u wanna get two awesome and classic games for the xbox 360 for the price of one you can get a dual pack of the games bioshock and oblivion which both have great replay values. I promise you won't be dissapointedWhat game should I buy for Xbox 360?
