Change that to a plot that makes sense. It started out as OH HI DEFEAT THIS SORCERESS PLZ and then you went to the PAST randomly and the Sorceress was actually good and took care of you when you were little and then it turns that ACTUALLY you need to defeat a future sorceress or else it's the end of the world. There's such a thing as over-complicating things :/

Still, at least final fantasy can't be interpreted in a gazillion different ways like Silent Hill, which is something.
