In an interview with Famitsu, "Final Fantasy 16" director Hiroshi Takai and producer Naoki Yoshida revealed that it takes about 35 hours to complete the main process of this work, while the full collection takes 70-80 hours.

Hiro Takai and Naoki Yoshida said that considering the players' busy life outside the game, when they are creating the main story of "Final Fantasy 16", they hope that players can complete the main line by doing only the minimum content when they cannot complete any side missions. The production team originally had a goal of 20 hours, but after constantly adding additional story content, the game's main line ended up reaching 35 hours.

"At the beginning of the game development, I think the gamers are really busy with things outside the game, so I hope they can at least aim to complete the main story," Yoshida said. “I think it makes sense to make the game work in about 20 hours, but more and more content is being added.”

　　In addition to story mode and side missions, there will also be a New Game+ mode called "Final Fantasy", so players who want to experience the game for a long time don't need to worry.
