i don't own any ps2 games. i had a ps2 for a while, and even modded it to play burned games. then i got an xbox when it came out. 6 months later i traded my ps2 to a friend for an unlocked cable tv box so i would get free movies, free pay-per-view, etc, because i had stopped playing my ps2 almost completely. right now the only console i have is a 360, though in the past i've gone through almost every other console that was made (except for the gamecube).
and i stopped buying games 2 years ago (i use gamefly) because i play them till i beat them (a few days to a few weeks) and then i pretty much don't play them ever again. so right now the only game that i own is project gotham 3, but only because i got it for 5 bucks shipped from gamefly after using coupons they had given me. (i haven't played it since the week i got it, after i got gold medals in everything and platinum in some.)
i haven't played a wii yet, and although i think i'll get sick of it after a few hours i try not to hate on it at all until i play it. i haven't played a ps3 yet either and the only thing i've hated on about that is how stupid i think it is to buy one now, before they do updates and have a decent library of games out (i didn't get a 360 until september). i'll probably get one next fall, when the library of exclusives makes it worth it.
