Let's say, instead of ridiculous time travel stuff and weirdo gods giving people Time Poisoning and 13 days to save a splinter dimension that just sorta appeared, let's do a completely different kind of Final Fantasy sequel.
I'm talking a Watchmen-style deconstruction game. Instead of fighting weird creatures and silly anime dudes in stupid costumes, the game takes place like 20 years after FFXIII, when all the characters are old and worn and depressed.
Lighting is a lonely government killer with nothing in her life other than fighting, she could never find any kind of happiness in peace so has been working as a mercenary for years looking for a battle where she can die honorably. She sometimes calls Serah, who lives alone with a lot of cats, since she and Snow got divorced eight years ago. Lightning had a kid at some point (the father was just a fling and she doesn't talk about him), but she's a terrible parent, really overbearing and bipolar and the daughter hates her. Snow is an alcoholic and massively fat. Vanille and Fang are still frozen. Sazh is the most mentally sane, but he lives a quiet middle class life yearning secretly for all the limelight again. And Hope has become a media whore selling action figures and writing books about their adventures.
The game is just twenty hours of you playing as Lightning's daughter meeting up with the old crew, trying to understand her cold mother. Finally the daughter and Lightning cry in each other's arms, and the daughter, feeling somewhat better about things, goes off the college.
