I'm looking for fun PS3 or Wii coop games to play with my fiance. So far we've played the following together:

PS3:
Little Big Planet
Little Big Planet 2
Castle Crashers
Borderlands - I was surprised how much she liked this.
Gran Turismo - She is horrible and I can't suck enough to make it remotely close :/

Wii:
Kirby's Epic Yarn - Her choice, I was miserable :/
Wii Sports
Dokapon Kingdom
Mario Kart - Free with the system - Didn't like it
Rayman Origins - Currently playing

I got bored of Resident Evil but I think the next one will be RE5 because I've had 3 couples recommend it already.

I'm open to any suggestions.
