According to Final Fantasy 7 Remake's Producer Yoshinoro Kitase and Director Tetsuya Nomura, the game is simply too big for a single release. As a result of this, Final Fantasy 7 will be seeing an episodic release, similar to the likes of Telltale games.
This revelation left they community wondering exactly how big FF7 Remake is and how many episodes will be released. Square Enix didn't spare the community any details on this, in fact, they wouldn't even hint at how long fans would have to wait between episode releases.
However, Square did clarify something to Kotaku:
"It means instead of concluding in one entry, multiple entries are being considered in development. Each entry will have its own unique story. As a gaming experience, each entry will have the volume of content equal to a full-sized game."
It's not the most detailed oriented statement, but at least it offers a little more context. It's interesting to note that Square Enix decided to take the episodic approach to the new Hitman game as a digitally released episodic game. When the story arc for Hitman releases, a physical version will be released.
I wonder if the two games will share a similar nature.
