well sony has actually been on top of there game (for once) with the software emulation although if you choose the ps3 buy a 60 gig. it has both PS2 and PS3 hardware in it. which has super high compatibility (i own a crap load of ps2 games, the only errors i get out of them is normally sound glitches or slow frame rates for a few seconds)
allows a console to play previous generation games such as the xbox 360 allowing it to play xbox games or the PS3 allowing it to play PS2 and PS1 games
i have to agree with this. i loved every ps1 game they released and most of there ps2 games
only thing i have against 360 is the annoying "points" thing they use to price there items. PS just strait up tell you it cost [insert amount] and i choose ps3 over 360 because of the outstanding amount of hardware failures i read they had. but everyone has to admit, 360 owns the ps3 in terms of games look at the exclusives and see which ones you like better
