Final Fantasy 7 could come to iOS and Android one day, but right now the game’s file size is making it somewhat difficult. Developer Square-Enix has stated that it may have to wait “years” for a mobile port to become reality.
Speaking with Shacknews, series producer Takashi Tokita said on the matter, “Unfortunately, it’s not that it’s not impossible for us to develop Final Fantasy 7 for mobile. It’s that currently, space will be an issue. Phones won’t be able to contain the space it takes. It’s over a gigabyte. People are probably going to have to wait a few years.”
Square is currently working at bringing Final Fantasy 6 to iOS and Android this winter.
