Well I'd also like to mention that the PS3 just got past it's year mark, comparing it's first year to the 360's current library is a bit prude wouldn't you think? All things considered I think they have a great selection of games, definitely more geared twards the hardcore, but they have plenty to go around I'd say. PSN titles are a bit more diverse, and lean much higher on the "casual" level, games like Calling all Cars, or Pixel Junk Monsters, fl0w, super stardust, everyday shooter, Pain, etc etc.
@Onna, sorry to see you so disappointed with it :( But every generation so far Sony has delivered gaming experiences on all fronts, I have no reason to believe they wont this generation. However if you do come back, you'll have some of us here to welcome you :P I'd seriously recommend some PSN titles ^^;
