- Animate the battle backgrounds, characters and monsters.

- Redo the music! And do it right!

- Make a greyed-out entry appear in Gau's Rages menu when you've encountered an enemy, but haven't learnt their Rage yet.

- Make the Rages more interesting somehow...90% of them are Attack/Special.

- Voice-acted cutscenes are becoming the norm these days, and I welcome our vocal-chord-vibrating overlords! But include cutscenes with more action, as well. There isn't enough action in the cutscenes for FF4's remake.

- Mostly unrelated: Make a prequel that tell's Shadow's backstory.
