If you could change one thing about FF7, what would it be?

On second thought, I would probably change it so that Emerald Weapon rams a certain area below the sea and opens up a secret area where you can gain lots of über-strong weapons and Materias.

And what would you do with the über-strong weapons and Materia? The strongest enemy (arguably) would already have been defeated.

To make that work you'd need to have some enemies even more powerful than Emerald and Ruby.
