Castle Crashers, get a few buddies and play through it for a while.
gears1/2, any halo.
Dude I love left 4 dead its a great co-op game
Earth Defense 2017 is pretty fun with a friend. Very simple, ''pick up and play'' game. I played through it with my gf. Right now we're going through GoW and that is obviously a good game. Next we're hitting Halo 3, and we also played through Castle Crashers with her brother, and that is another ''pick up and play'' game, with not many controls to learn at all.Rev
Castle crashers with a few of my buddies was my fav co op experience.And back in the days conflict desert storm for xbox, i had so much great memories with my buds chilling.I only wish they had more 4 player couch co op games.

Good list(only didnt played the first Vegas nor Halo Wars.

Ulimate Alliance is another, and so were the Lego Star Wars games.
Not the best, but really under rated, is Army of Two, is has fun co-op.
Gears 1/2 and RE5 have given me the most enjoyment as far as co-op goes.
Gears 2 is amazing in co-op.
Castle Crashers is total fun.
www.co-optimus.com has a big list of games and tells u if stuff is online or split screen co-op
James bond: Everything or nothing
My favorite game to play co-op in is Halo 3. Fill up a warthog and go chase some grunts.
The only game i play co-op on is Splosion man from arcade... Its quite annoying :P
How are people forgetting? What about Rock Band games?
Rock Band 2. Only co-op game I could have fun with. Split-screen coop shooters are snoozefests in comparison.
Left 4 Dead all the way. It is just awesome when you and your three friends go on versus and kill all survivors right outside the saferoom. :twisted:
