What is the best xbox 360 game ever?

Bioshock hands down.

Definitely Bioshock. It had everything. Good graphics, excellent story, engaging atmosphere, and realistic sound effects.

Hey guys, can we please keep this to exclusives? In my opinion, that would be more interesting but oh well...never mind -.-Kimbo_Slyce

There's no such thing really as the 'best' 360 game, there is the most popular 360 game but not the best. People wil have a game that in their eyes is the best 360 game but all that is is opinion and in my view opinion does not dictate what the best game is. But anyway my favorite 360 game is Mass Effect, fantastic story and visuals.

Dang I can't believe no one said the usuall... I mean it is the Best game actually lol and usually people say it is..

OBLIVION!

Gears of War 2 all da way ARONMAN6

Halo 3 because of all the DLC.

Bioshock

My favorite - Mass Effect
Exclusive favorite - Culdcept Saga

There are so many good games, but i would have to say Fallout 3 because of the endless amount of fun, options and missions.

Forza 2

Bioshock or Mass Effect

BIOSHOCK.

exclusive= Gears of War 2
