Desperately would love to see a Final Fantasy 7 sequel based on the events of AC (If we're looking at the game in parts, part 1 of the game would be the AC movie, Part 2 and 3 would explore afterwords)
BUT, it must be done in the original FF7 style. The only thing I would want to change, is to make the battle system more like a CRPG, specifically like the battle system of Divinity:OS2.
