A couple of days ago, Sega released a demo for 7th Dragon III Code: VFD onto the Japanese eShop. It’s a limited demo; there’s no character creation and the level cap is 10 for characters, but you will be able to play through to the beginning of the first chapter (similar to the Stella Glow demo.) Additionally, character data from the demo save file can be imported into the full game when it releases, allowing you to edit your characters from the demo.
Sega, through an official 7th Dragon Twitter account also announced the release of the demo and the bonuses of demo participation in this Tweet. It’s always a nice thing to see them having a presence like this in promoting their franchises.
7th Dragon III Code: VFD is due for release in about two weeks (October 15) in Japan. Previous games in this franchise haven’t been localized. This could be the last game in the 7th Dragon series – it remains to be seen whether or not the game will be picked up for localization. The story for this game might be seen as self-contained enough to merit localizing in spite of the previous games not being brought outside of Japan.
