Many fans had been wondering about the music featured in the latest promotional footage for Final Fantasy XV’s upcoming demo, Episode Duscae. In the video, Square Enix used a rendition of the classic Final Fantasy main theme, which has been persistent throughout the majority of the long-standing series. The song’s inclusion in itself wasn’t too surprising – after all, we’ve already heard bits of the Prelude – but it was the familiarity of the arrangement itself that was throwing people off. Composer Yoko Shimomura took to Twitter today to attempt to quell much of the speculation.

In a self-proclaimed notice, Shimomura confirmed the Final Fantasy main theme heard in the recent Duscae footage was from Distant Worlds, and not one of her own arrangements. She says it’s a very nice piece of music and as a result feels a lot of pressure. In Episode Duscae, we’ll be hearing both arrangements of music from some of the game’s previous trailers as well as new compositions. Shimomura would like fans to look forward to it.

Final Fantasy XV Episode Duscae will be available to download upon the launch of Final Fantasy Type-0 HD. Included as a first run bonus, the demo code will come packaged with all early copies of the game when it releases in March worldwide.
