Only if you ignore Crisis Core, Before Crisis, Dirge of Cerberus and Advent Children
And we are going to ignore them because none of those games "complete" the story of VII. They all came after the fact to basically cash in on its popularity. Much like the remake.
They where a thing when the company started the Remake. If people are going to complain that Final Fantasy VII Remake is not the whole story, that is fair because it is not, but neither is the original release.
