A New Idea That Interested Me!

So I've been playing random games here and there and thought of a great idea... What if they made a Final Fantasy game where the story is never the same (Changeable due to your actions in the game). I think this would be booming in sales. Not a online multiplayer game for I know the current FF series of online games kinda are like this in a way. A Single Player game. Best part would be the beginning when you choose your race! Any other ideas that would make this game great? I'm all ears! :woot:
