I'll be honest, I want them to keep whatever they can without getting in trouble, and only change what is needed. If they can keep the majority of the story the same (New York City, Aya Brea, being from within trying to take over), I'll be mostly okay. Though I suspect with how things are these days, it'll likely be an ARPG on the lines of FF7R. Which...actually might work better for only controlling a single character.
