Heavy Rain and Socom are on your exclusive list? I was a HUGE socom fan for PS2 but the ps3 ones are garbage. I really like Uncharted but Gears of War is amazing and you didn't list Fable.
I was just listing exclusives at random, it doesn't really mean one's better than the other but the PS3 clearly has the advantage in exclusives, I even left out Resistance which is a huge hit.
I've never played Fable either so I don't know if it's good or bad.
