PS3 games...?

OK I've played formula1chmpionship it was OK not special. NBA LIVE 08 didnt like it I prefer pc version less graphics. All star football ps1 graphics lol why when i have madden lol. rachet and clank ehh kids game. NOW WHAT? COD4 i hear is amazing but ive been told graphics arent great but gameplay is great and I'm not a big fan of 1st person shooters . I prefer 3rd person. I love the idea of asins creed but looks too repetitive for lasting appeal. Any thoughts on games to buy? Also if it's complicated I wont like it.
