As it says in the title, what's your favourite Xbox 360 Game? And why?

Mine, is halo 3. Rocket race online is the best game ever created, I think. :P

My favorite for 360 right now is also Halo 3, although I do not like rocket race haha. It's my favorite simply because I like the feel of it better than many other games, and I'm just as willing to play it now as day 1. (it hasn't been that long, but I'm confident I'll be playing for years)

Halo 3 as well. Although i do not play any objective game types, only doubles and slayer.

I have a PS3 but my roomate has a 360 and he buys all of the good games that come out. Not a big fan of GOW but i think BioShock and Mass Effect are 2 great games everything else is either multiplatform or not good.

Yeah yeah lol Halo 3 is ok but I only enjoy the online and the graphics suck.

halo 3. and medal of honor 4

Gears of war

Hands down my favorite 360 game to play right now is Call of Duty 4. I believe it is the no. 1 played game on Xbox Live at the moment. It's sad to hear Call of Duty 5 will be returning to WW2. But then again Treyarch is developing that game not Infinity Ward.

Guitar hero?

Towel Wrap Adventures

Mass Effect, Kameo: Elements of Power, and Flatout: Ultimate Carnage.

They're fun, that's why I like them

Bioshock, Mass Effect, COD4, GOW, (The Orange Box as long as you don't play TF2, controls kind of suck)...ALIEN HOMINID HD!

I have never liked playing FPS games on a console. Especially the 360. The mouse is just so much more precised. Also many of the 360 fps games are plagued with auto-aim assists and bigger hit boxes. It just screams "Here let me help you aim better". I feel like I'm being helped to play better. NO THX!

Mass Effect And Halo 3 are the best.

Halo 3 and Frontlines fuel of war. :-0

C&C 3

the only reason why i bought a 360

also call of duty 4 id pretty good too!!!
