PS3 split screen/co op games

I've got a 'mate' coming over in a couple weeks, and I know she digs PS3. I haven't touched my consoles in a while, and was jusy hoping that you guys could make some suggestions for decent split screen, or single PS3 co-op games. She likes Rayman. Is Origins a co op game?

Yeah up to four can play it. I recently downloaded it and it is really good. Definately worth the purchase.

Also Little big planet 1 and 2 is good to play with someone, im currently playing resistance 3 co op and its quite good... and im not a shooter kind of player...but this one is fun, also killzone 3

i dont know what else... sports games, playstation move games, etc...
