i dont have an xbox yet but im going to get one, someday, because i played Halo at my friends. its a tad boring but seeing halo 2 made me want one even more. plus there are several other games for it i would want.
i agree that a lot of ps2 games arent good, but i like rpgs (A LOT), and for a little while psx was the rpg king. it was toppled by the gba, though. dont get me wrong, the only reason i like ps2 and psone is the companies working designs and square enix. without them my rpg collection would be CA-RAPPY. i also like the dvd function of my ps2, so i didnt have to buy a dvd player.
the psp may fail against the ds, but im getting one anyway...
i like the entertainment extras, but im not getting a psx, because i dont want to waste 1000 dollars on a fancy ps2.
the gamecube, however, is relasing some very good rpgs, too. the n64, in my opinion, did not have as much rpgs as ps1, but some were better, but i think ps1 had more rpgs that were about as good or better than n64 rpgs.
