Yea Fable II is pretty poor co-op. Player 2 is seriously restricted, i.e. can't even open doors and camera angles are really bad.
I'd go for World at War. Nazi zombies is amazing tbh, campaign is good but you don't actually unlock the levels as you go along in 2-player for some reason. So you'll have to complete the game in single player first (or play 2 player all in 1 sitting).
