I would guess most people know that I'm a 360 lover, so when I say that the following two PS3 games are in my top 10 of best games this gen, it should mean somethign! HAHA.
I highly recommend Uncharted: Drakes Fortune (it was a superior SINGLE player game to Uncharted 2 IMO) and Valkyria Chronicles.
Edit: Under the Radar. ARGH. Sorry. No help here :(
