Why do companies do anything?
I haven't seen the ending of FFVII so I honestly can't say if it's that vague or not. Having an open-ended ending for a movie or a game isn't always a bad thing though. Using FFXIII's open ending as an example, wondering what happened after the ending of that game is like wondering what happened to the seven dwarves from Snow White. How did the dwarves make ends meet after Snow White left? Were they able to keep their house clean? Was their mining operation successful? These questions are never answered because the focus of the story isn't on them, it's on Snow White, the prince, the witch, and strong subliminal context. Similarly, FFXIII was about the main characters' struggles as L'Cie and FFVII was, ultimately, about Cloud's struggle with his identity.
Again, I haven't seen the ending of FFVII, but I assume that they wouldn't have made it so ambiguous as to warrant a sequel movie being made of it to explain what happened. At least not in 1997 before Square was the financial equivalent of Disney in Japan. Nowadays I wouldn't put it past them. I mean hell, look at what happened with FFXIII.
SPOILERS FOR A 1997 GAME
After defeating Sephiroth, Cloud and the others escape from the Northern Crater as Holy awakens, watching from the Highwind as Meteor crashes into Midgar. Holy is there to hold it off, but it's not working, only creating even more destruction. The Lifestream surfaces from the Planet and joins with the Holy spell to stop Meteor. The game literally ends with Holy/Lifestream holding off Meteor as Midgar is destroyed with no chance of salvation whatsoever before transitioning to Aerith's face, alluding to her being the one that helped bring the Lifestream to the surface to try and hold off Meteor.
And that is literally how Final Fantasy VII ends. It took the 'On The Way to a Smile' novellas and Advent Children Complete to help carry on from the original.
To me, the story wasn't over. It wasn't over until Cloud confronted his past guilts and came around full circle, which is what I feel that Advent Children Complete did quite nicely.
