Like the titles says, where can I get the Iternational Version, and will it work on an American PS2. There seems to be a lot more, and I wanted to play it. And how much is it too?

Play-asia.com or lik-sang.com or really any other import site. You'll need a modded or Japanese PS2 to play it though.

BLAST!!!!!

Modding your PS2 is pretty cheap if you can find someone who can do it really well. But I wouldn't go through all that just to play Final Fantasy X: International... nothing much is in it anyways. Dark Aeons, Expert Sphere Grid, Install to Hard Drive function.... that's about it.
