Regarding a release on other platforms…
Tabata: “I’d like to release the game on PC as a technical attempt. I want to show PC users Final Fantasy XV running on high-end machines, and we personally would like to see it, too. Also, I would like to try developing on PC to pursue a unique way of playing with PC-exclusive features like making your own quests and enjoying the world using things like mods.”
