The shape of the trilogy
What Rebirth changes, without spoiling how
- Zack is alive in a world that runs beside this one, and the game cuts to him. The original's ending for him is the thing the trilogy is arguing with.
- The Whispers are gone as a system and present as a question: every departure from 1997 is something the story now has to own.
- The Nibelheim flashback is played, not narrated, and it is the first chapter.
- The ending of the Forgotten Capital is the trilogy's central change and the reason chapter 14 is discussed more than the other thirteen together.
- Cait Sith, Vincent and Cid arrive where they did in 1997; only the first is playable.
