Final Fantasy V is making its way to Japanese smartphones later this month, according to a report by Japanese FF mega-site FF-Reunion.
The Final Fantasy series has been gradually been making its way to modern phone devices - first with versions of FF1 and 2 based on the PSP ports of those games, then the 3D DS versions of FF3 and FF4. This version of FF5 is said to be based off the Game Boy Advance version of the job-switching title, though is said to feature redesigned menus and some minor graphical improvements.
All of the other mobile-bound FFs mad their way West relatively quickly, and we expect the same here. We'll inform you when there's any movement!
