As far as I know, anything for the PS1 has been discontinued at this point. FFX and FFX-2 are both on greatest hits, so you can probably still buy them new. Support for FFXI for PS2 has been dropped, so you'll have to scramble to find it, and even harder to find the Chains of Promathia expansion. You can still register a new account for it and play it, but there aren't going to be any more new units made, meaning the number of PS2 players is now finite. It'd be a LOT easier (and cheaper) to buy the PC version. FFIII may or may not come to the PS2. There have no announcements regarding this possibility. I wouldn't be too shocked if it did though.
