I'm looking for something to try on my new PC:
2.0ghz amd athlon64 +3200 AM2 (oced to 2.3ghz)
512mb DDR2800
ATI Radeon X700SE pci-e16 (also oced)

I'd like an Action-Adventure, a Platformer, or an turnbased RPG (like final fantasy)

Any recommendations?
PS: NO FPS. I have too many as it is (Doom3, HL2, FEAR, COD2, UT2004)
