It's on PS2 and PC, but in order to play on a PS2 you have to buy a hard-drive for your PS2 and hook your PS2 up to the internet. That means you can't use the "newer, slimmer PS2" to play FFXI. Also there's a (about) $15.00 subscription fee to play the game (+ $5.00 per extra character). If there's any other info you'd like, you should do a search for some reviews.
