Excellent game, though not necessarily worth it over the US version.
Kingdom Hearts is excellent. It hasn't aged as well as many action games, sadly, as it's somewhat clunky. If you have an opinion on Kingdom Hearts and are wondering if the Final Mix version is worth it, to this I say, only if you're hardcore. The differences are mainly in a few new abilities and one super boss, and a new secret movie (which, if you've played KH2, is moot). For me, it was worth it, but I eat Kingdom Hearts up.

Kingdom Hearts Final Mix (Ultimate Hits)
The original Kingdom Hearts was something like I've never would expect of two famous companies coming together as one. This International version, Final Mix, is the same game as the original Kingdom Hearts, but with really cool and awesome extras added in that even the U.S. or European release never had. The game is in English dialogue with Japanese subtitles, but if you remember the menus alright from the U.S. version, it'll be a piece of cake!

Fast Shipping for an awesome game! ^_^
You guys can't miss this game!it only had taken 5 days for the package to come!thank you very much,guys of Play-Asia! ^_^

secret boss
This game is pretty much kingdom hearts 1 with a few bonuses such as an extended KH 2 trailer and a secret Organization boss in Hollow Bastion.

i am either beautifully misinformed or
This game contains the secret fmv that promotes the second game, deep dive or something, a half dozen extras, and is mostly Japanese, if not completly

worth buying :)
