Famitsu and Dengeki have both posted interviews with Tetsuya Nomura and Yoshinori Kitase today about the Final Fantasy VII Remake, confirming that they are outsourcing the project with another developer, talking more about the battle system, why theyre splitting the game into episodes and more.
Final Fantasy VII Remake is a multi-part series. Please tell us more about this decision.
Kitase: The idea that a remake of Final Fantasy VII would not fit into a single release was there from the very beginning. We still cant share more information about its multiple parts, but please look forward to future announcements.
Nomura: If we dedicated our time to a single release, parts of it would become summarized. Wed have to cut some parts, and additional parts would come in few, so rather than remake the game as a full volume, we decided to do multiple parts.
Kitase: As you can see in the trailer, we showed Sector 1 and Sector 8, but in those areas alone, I think you can see a lot of density. When youre remaking the entirety of the original version in that quality, its not possible to fit it all in one release.
