What PS3 game should i get?

Ok im getting the PS3 on saturday, and i have no clue on what games to get. Please don't say Metal Gear Solid 4, Little Big Planet or Killzone 2. I already played LBP, and MGS4 and i dont really like them, and ill be buying killzone when it comes out. I just need like 2 good games to start off with. Yes i will be playing online. Make a lot suggestions please cause i will be buying 2 and i also have Gamefly so i can rent even more. Thank you.
