Being Final Fantasy a very historical series, its fans are spanned across a lot of different platforms. Modern gamers may have started playing it on PS One and now, who knows, they just own a PC to play their favorite titles, so they are basically blocked from playing new Final Fantasy games.
Although Square Enix has started releasing older Final Fantasy console titles for PC, it seems in the future there are very few chances to see Final Fantasy XV on that platform, maybe through Steam or whatever. Director Hajime Tabata was pretty clear discussing it during the Comic Fiesta.
“Really?! Where did you hear this? If anything, it is a misunderstanding. There will be no PC port. We never planned for it. The game is originally developed on the PC first and what we said was how the pre-beta works very smoothly on the PC and now optimizations are being made (just like any beta testing would be like) for the consoles. Please do not misunderstand.
IF a PROPER PC version is to be made, then many changes have to be made and a lot of things have to be reconsidered before such a move can be made.”
It doesn’t seem to be a total closure about the chances to see Final Fantasy XV reaching PC, but for now Square Enix doesn’t plan on a simultaneous release for that platform and Xbox One/PS4. In the future, we think something like Final Fantasy XIII could possibly happen, perhaps based upon the success of the trilogy recently released on Steam.
