They also made an FF7 International, and the Kingdom Hearts games have a "Final Mix" version. FF12 had an International version that makes the original game a complete waste of time.

They always include English voice acting, because Japanese people really, really like to hear the English voices. Japanese developers still can't understand that we might like to hear the Japanese voices. Supposedly, we Americans don't care/like Japanese stuff at all. But, they've been talking about releasing an International version of a game here in America for years, only with Japanese voices (and English text, obviously). Cross your fingers; voice acting in these games tend to be a lot better in Japanese than in English.

Just in case you wanted more information on the international line, in general.
