Earlier this May at E3, Square Enix announced that a mobile prequel to its legendary RPG Final Fantasy VII was in development. The title of this prequel has been announced as Before Crisis - Final Fantasy VII. The game is set in Midgar 6 years before the events of FFVII and players will be in control of a member of the Turks.
The game is slated for a September 2004 release in Japan, and it will be available on NTT DoCoMo 900i-series or higher phones. A North American release date for the prequel has not yet been announced, and it is likely that the FFVII:BC will not be a downloadble option for US Gamers in the future given the disparity between Japanese and North American handset technology.
Also, according to the FFVII:AC official site, the release date in the Info section has been modified from Summer 2004 to a vague 2004 timeframe. It seems that fans will probably have to wait a little longer to for this anticipated movie release.
