What if Aerith Survived in FFVII?

Would it change everything in the game, or would it all stay the same. Without the sadness in the area of the game how would it all turn out...no depressed cloud??? That would be like, totally boring, I mean...C'mon man, how bad can it get...That is the point of a "failed love story" the very thing that made Final Fantasy famous!! There is no game without that! FFXII wasn't that bad, I'll admit it, but the lack of a basic storyline and a male female correspondence ruined it as far as entertaining gets, I basically just got really bored with it. any way (back on topic) Aerith dying was crutial to the amount of entertainment I could get out of the game so it shouldn't be changed.

p.s. Tell me if you disagree with this statement.
