Over HALF of those game's either are on ps3 are came out before ps3. I mean if you gonna make a fair list make it when ps3 came out and later. Plus some of those games came out on ps2. If you're going to make a list please put some effort into it cuz that is the worst comparsion i might have EVER SEEN!!!
