What do you think the best xbox 360 game is?

I need a new xbox 360 game, I enjoy first person shooter's and role playing games. Please don't say Call of duty or Dragon age, I already have CoD 2,3,4,5,6,7 and Dragon age 1 and 2. Thanks :)What do you think the best xbox 360 game is?
easily mass effect. i would start with 1, then move to 2, with 3 coming out in nov. and you get to continue your gamesave from one title to the next(the coolest feature by far).



after that?



well, alan wake is pretty interesting.



ace combat is, well, ace combat.

forza 2 or 3 if you want a racer. or NFS: hot pursuit.



lost odyssee if you are looking for an RPG.



other than that, the rest is forgettable.
I have this pretty cool game called "Far Cry 2". You go to Africa to take out a guy that is selling guns to two different sides in a civil war which is just killing more people. It also has Xbox live and you can create your own maps. It also has a 50 hour long story line.What do you think the best xbox 360 game is?
Oblivion! There's a new one coming out 11/11/11 called Skyrim. You could try Fall Out: New Vegas - it's quite dark, but really fun! If you want a game unlike the ones listed, I recommend Kingdom Hearts or Tales of Vesperia. Both are Japanese RPGs and incredibly addictive and fun to play.
all the battlefield games, medal of honor, halo 2,3, reach, half life 1 and 2What do you think the best xbox 360 game is?
Since you like Dragon Age, I would get Mass Effect. It was made by the same people. Also, I would try Bioshock, it's a horror FPS.
Halo Reach.

Gears of War 2

and Gears of War 3 in September.
Battlefield: Bad Company 2
