I play MP on PS3 as well.
I should hate this game. While the MP is good (Especially Light Cycles even though it tends to always be the same map), the single player is so dull and repetitive. But I beat it and am going on a second go. Is it cuz I love the world/license around it, or is it the MMO-like leveling up system? It's funny. I should hate this game, but I'm addicted.
