Final Fantasy 7 Rebirth’s sequel reportedly has a finished story, and I’m very curious to see how the trilogy handles one major theme from previous Final Fantasy games. Final Fantasy 7 Remake and Rebirth teased some potential changes to the story of the original game. If anything, the new games feel like their story is in conversation with the original as much as it is recreating it. While playing the original Final Fantasy 7 isn’t necessary to enjoy the new games, players who know the story may catch some hints at potential changes in the as yet untitled Part 3.
