As far as I’m concerned there is only one Final Fantasy VII. The original game that came out in 1997, that’s it. It told a complete story from start to finish and that’s the story of final fantasy VII.

Everything that came after wards, Advent Children, Crisis Core, Remake and Rebirth, that’s all fan service fanfic to please the fans and give them additional material to jerk off over, but it’s not the core base story.
