Hmm, you don't like RPGs eh?
Well, Medal of Honor: Heroes 2 has 32 online multi, both Syphon Filters, Patapon, Crush, both GTAs, the sports games are great if your into those, MGS: Portable Ops if you like Metal Gear.
Killzone: Liberation is a very good top down third person shooter. Much, much better than the Ps2 game imo. Also, the new God of War game is looking superb. If you can find ten games, then Id say its worth a purchase.
