Yeah, but again, it is hardly inferior by a large margin anymore. It is down to shit like the shadows in DMC4 being different, or a slightly lesser resolution. The days of Turok (lol) looking like garbage on the 360 seem to be over. Nothing very tangible or anything that would destroy the experience. Even Madden is now neck and neck on both systems and no longer has the gimped 30 fps PS3 version. Are the 360 versions still the best? yes, like you said; but PS3 only owners, or even those who just want to buy a game on PS3 for some reason (like me buying SC4 on PS3 because of my arcade stick), no longer get the ripped off by comparison.
Thinking back, it was actually sad how horrible the PS3 ports used to be. Hate to bring up Turok again, but that was just some sad shit. I only did play the demos, but it was ridiculous how lazy the PS3 port of it was.
Just counting my game collection, I would say that I have a little less than half the amount of PS3 games than 360 games.
