You may be aware of an upcoming action RPG known as Reynatis for PS4, PS5, Nintendo Switch and PC - we'd never heard of it because of the lack of Xbox version, which the game's creative producer touched upon in a recent interview.
Basically, it's mentioned that a general lack of interest in Japan for both an Xbox version of the game as well as the Xbox platform itself is the reason behind this - and the same goes for all of publisher FuRyu (NIS America)'s titles.
Here's what creative producer TAKUMI had to say to Touch Arcade earlier this month:
"Personally, I would like to do Xbox versions of the games but the reality is that in Japan there’s not enough demand from consumers. There’s not enough recognition from consumers for the platform itself to be able to justify being able to make an Xbox version."
TAKUMI also went on to explain that adding another platform to the development cycle would be challenging as well, and the team doesn't actually have any experience working with the Xbox platform.
It's obviously a massive shame that we're not seeing Reynatis or any other of FuRyu's games on Xbox, but if the company feels like it's not worth the effort, it's hard to argue with them! Hopefully one day things might change though.
