Killzone 2 or 3 and Uncharted 2.
Only one vote per person please, those who have chosen multiple titles so far, I'll only include the first game listed.
Heavy Rain, just an amazing experience, nothing has come close (my 2nd pick is GOW3). Heavy Rain for the win!!!
Wipeout Hd make your eyes bleed fast with weapons chucked in for good measure,already a legend in it,s own right the wipeout series has evolved over the years and the PS3 version is fantastic to play and look at
