@Ranmaru That's sort of a surprising reaction! Having the original JP voice track is a given these days in almost anything.
I was personally taken back at the dub existing considering Sega's modern otaku focus, the content of this game and the logistics of its age and release.
I sort of imagine it was a Microsoft request foremost, but it is probably a good path to take considering I still feel like the release of this is to begin a worldwide path for PSO3. Sega has been doing a reasonable job of making up for earlier transgressions in recent years.
