Naoki Hamaguchi says the main story and ending of FF7 Revelation will not change, but the the side elements outside of that will change drastically based on player choice!
He says rather than having something like multiple endings, they believe that conveying "this is the correct story" is the more right approach for this game.
However, the side elements that are not the main story will change based on player's choices. He says based on those choices the gameplay, storytelling and how characters inner selves are portrayed can branch out quite drastically.
Each character faces a final battle with their own motivations and feelings and people's attachment to each character will differ from player to player through their own game experience.
