I personally love Uncharted 2: Among Thieves. Perhaps you've heard of it.
It has some great Multiplayer, which is loads of fun. If you like plataform / shooters, give it a try.
Oh, and add me to the PSN if you want; my ID is Raskbuck
Hey I see you are a PS3 fan too. What are some good ps3 games you play? I bought Modnation racers when it was released, but I haven't really seen any games worth buying yet.
