They don't have to do it for everything. Just for smaller things. They actually did allow you to choose what your character said much more often in VII and VIII than they have in recent games, where it's all basically a film where you push buttons in order to get to the next scene. They didn't do it with everything, but they definitely did it more often, and in some cases your answers affected how parts of the story played out. I think that's a fantastic way to do things.
