This looks intriguing, but there is one problem that turns me away from it - the difficulty. My ideal FF6 hack would change everything as you did, but kep the difficulty roughly the same as the original UNTIL the WoR, where it would get much harder than the original (only after you've acquired the Falcon.) This is the type of hack that I'm working on - I know most hackers like to make hacks that are much harder than any game developer would ever dream of making their game, and I just don't find that fun. That's not to say the original game was ideal, I would consider it too easy, but that's mostly due to abusable glitches and a low experience curve only, and as a result, endgame was a complete pushover. However, if I'm just trying to make it through the WoB and I have to keep resetting because I keep dying over and over, the game is too hard. That shouldn't happen until endgame.
In short, a hacked game shouldn't be any harder than a LLG in the WoB.
