I don't think I've seen a thread like this, so I'm going to start one myself.

Let's imagine that Sephiroth doesn't kill Aeris. How would this affect the game? Not having played through this game entirely, I couldn't really come up with a good answer, but I'm sure most of you would come up with crazy theories on what might have happened and how this could affect your opinion of the game. Would it make this game better, worse, or would it really make no difference, just that Aeris is still alive. Would you still like this game if Aeris doesn't die?
