Final Fantasy XV Director Hajime Tabata provided more information of the game's structure in a new interview on Famitsu.

According to Tabata-san, the game will include fifteen chapters. The first half will be open world, while the second half is more linear and story-driven. The purpose of this design decision is to prevent players from getting tired of the open world by tightening the game and giving them a taste of the traditional Final Fantasy story progression.

Playing only the main story of both halves will take between forty and fifty hours.

On top of that, we also learn that the "master version" that represents the game that was supposed to launch on September 30th, is now considered roughly 90% complete.

Final Fantasy XV will be released worldwide on November 29th for PS4 and Xbox One.
