You know what I'd like to see?
Right after the Floating Continent, the player should get to choose a character, not unlike the earlier "Choose a Scenario" section. I mean, in the original game, the player gets stuck controlling a character who is in a coma for a year.
Imagine getting to control Relm, where you have to use your art skills to con your way into a mansion to save an esper.
Or you can choose Locke and spend a year training and improving your "Treasure Hunting" abilities so you can infiltrate a massive cave in search of Phoenix. Since it's a 2-party dungeon, maybe you befriend some lackey along the way that you end up sacrificing for the cause.
Edgar gets to gain the trust of a gang of thieves and take on a whole new personality.
Terra's story could be a Persona-like life sim in Miranda. With all those teens and adolescents in the town, there's bound to be some drama.
Or, of course, you could play as Strago and just say "fuck it" and join a cult.
So many options! It's always bummed me out that the designers force you to play the most boring one. It's so dull that even the only enemies you can fight kill themselves.
