What are some good co-op games for Xbox 360?

-So I have an Xbox 360 and my games are mostly football and sports-related. I was looking for good, fun co-op games that I could play with my brother and actually enjoy while doing so.



By co-op, I mean 2 players - not online. I played a Teenage Mutant Ninja Turtles game on the PS2 and thought it was great.



Any suggestions?If you don't want to read all of this, just click the links and watch the videos for yourself. I'll give a description and then some links.



Crash Mind Over Mutant: This is a laid back platformer with some fun combat and a unique gameplay twist. So I won't spoil the twist, here's the link: http://www.youtube.com/watch?v=QFV5lbOKr鈥?/a>

Please forgive the low quality of this video and the commentators. There are no truly well-made videos on the site where I find these videos. There is a prequel called Crash of the Titans that has better videos for co-op. If you want to take a look at better videos from it, I'll give you better link for the prequel as an alternative: http://www.youtube.com/watch?v=2jEAjy6KI鈥?/a>



Now the other is called The Legend of Spyro: Dawn of the Dragon which is a more story-oriented game. If you want a good single player experience and to understand the story of this one, play the previous Legend of Spyros called The Eternal Night and A New Beginning (in backwards order. Meaning New Beginning is the first). Here's the link: http://www.youtube.com/watch?v=dOJph-S6d鈥?/a>

I used this video despite it's foreign language because of the high video quality and how it displays the co-op well. Both are local games, so no online as you wish. Hope this helps. They're very good games in my opinion and probably the best Multiplayer games I've played so far.
Gears of War 3's multiplayer is brutal, bloody (with spurting blood and squashed heads) and fast-paced 鈥?everything that fans of the series will love, but keep your eyes open, there are already skilled players around with high rankings. The chainsaw bayonet finishing move is as bloody as I remember it, as is the retro lancer's finishing move 鈥?where you charge your opponent and hoist them into the air.
HALO REACH OR ANY OF THE GEARS OF WAR
