Well, I am currently playing a rented copy of Heavenly Sword and I don't really dig it. My brother bought Uncharted, but I haven't gotten that into it because the demo didn't excite me really.
Ratchet & Clank is awesome however.
edit: Also add Nights: Journey of dreams on the list of ones that I ended up not caring for.
