I wouldn't suggest resident evil 5 tbh, it's not really a casual pick up and play style game, Halo 3 or Gears of war would be the best bets i think.
For some wierd reason I found the original gears of war co-op more more satisfying thanb gears of war 2. This might be in part due to my masochistic urges and the slightly lessened gore in GW2, but there you go. Happy days!
