Nomura and Kitase reiterated that the game will be fully voice-acted, though the cast may be different from those heard in 2005’s “Final Fantasy: Advent Children” film, and those characters who weren’t in the film have not been cast yet.
They also confirmed that there are plans to include both the dating events from the original game, and at least some of the minigames. It’s still undecided how those might be implemented. As evidenced in the PlayStation Experience 2015 footage, it’s clear that the team is interested in maintaining the original game’s atmosphere and story.
As for changes from the original, Nomura and Kitase mentioned that the new game might have a more open-world environment, though they were hesitant to use the words “open world” or “sandbox.” Characters’ actions may affect the environment, either way.
Final Fantasy 7 Remake doesn’t yet have a release date, and probably won’t for a while–Nomura said he intends to wait until both Kingdom Hearts 2.8 Final Chapter Prologue and World of Final Fantasy are released before sharing any further news.
