I could go into each of those and say why many suck or are over-rated (like LBP, which is a pretty mediocre game that only got fame because it's create-a-level content) or you using games that are not even out yet (Beyond: Two Souls and The Last of Us).
Gears of War is superior to Killzone and Resistance. Forza Motorsport is better than Gran Turismo. Crackdown is better than Infamous.
The PS3 has some good games, but not many good exclusives.
