Wreck-It Ralph - Takes place inside the Game Terminal and the original game worlds created for the first movie. The terminal would link to the three games, as well as a small area based on Final Fantasy Dissidia because you have to take that opportunity. The Fix-It Felix area would be small and mostly be a resting area, Hero's Duty would be more linear and heavy with enemies, and Sugar Rush would be more open, and where most of it takes place. Guest party members would be Ralph and Vanellope. No licensed characters would show up.

Enemies would be based on iconic Final Fantasy monsters like Goblins and Bombs. Maybe a Behemoth shows up at some point. Plot would involve Turbo coming back to life, most likely as King Candy again, because of something something hearts can exist in data. He'd be doing something to try and get back at Ralph. Bosses would be a Cybug that ate some Heartless, and is now half Heartless, and Turbo's Heartless, presumably something either bug or car related.
