Hatsune Miku is the world's most prominent non-existent pop star, so she's a natural fit for virtual reality. The PlayStation Move isn't exactly the world's most accurate VR controller, but it sure does have a glowing ball on the end, so it's a natural thing to wave at a virtual Hatsune Miku concert.
That seems to have been the design brief that came out of Sega when it decided to build a Hatsune Miku title for PlayStation VR. I played a demo of Hatsune Miku: VR Future Live at Tokyo Game Show, and I didn't come away with much idea of how the actual game will work out — it was minimally interactive, with some simple rhythm elements that had little in common with the actually-pretty-great Miku games for other platforms. As demos go, it was particularly demo-y.
The visuals are clean and attractive, though, while what you think of the sound will obviously depend on your predilection for Vocaloid-powered J-pop. I felt pretty silly waving my PlayStation Move around in the middle of a gigantic convention center, as did probably everyone else, but I could see people getting more into it in the comfort of their own homes. If that's your thing.
Hatsune Miku: VR Future Live will be released alongside PlayStation VR next month.
