Update: Game director Hajime Tabata explains that although a Master Version of the game has been completed and work on a substantial day one patch begun, he wishes for this major update to be included on the disc so all players can enjoy the game as intended.
"We completed work on the master version for FINAL FANTASY XV the other day," he explained. "You can think of a master version, as it is known, as what you get on the disc when you buy the game. We felt that the quality of this version will satisfy most players out there.
"And we are currently creating a gameplay video of about 30 minutes in length, based on this master version. The video is due for release on the 16th of August, so when it comes out please take a look and you can check the finish on the master version for yourselves."
He continues: "Our objective with FFXV was to deliver a FINAL FANTASY of the highest possible quality, to every single person who buys the game. We have completed the master version, but when it comes to that highest possible quality, we felt that we had not quite reached this standard yet.
"Accordingly, in order to make this master version an even better product, we have been creating a downloadable add-on known as a patch. This has been worked on with the intention of releasing it on the same day the game comes out, so it would be what people call a "day one patch".
"However, a patch is not something that can be applied by all players who have bought the game. It is impossible to provide this patch to everyone who plays without connecting their games machine to the internet.
"On top of that, the day one patch has pretty substantial content in it, but to me it feels as though it is still one step away from that truly ultimate quality we are striving for."
"I have been thinking about this ever since we completed work on the master version. We have put our whole lives into developing this game, with the intent of bringing the highest quality of game experience to every single player who buys it. And I personally started developing FFXV from a desire to let everyone play a FINAL FANTASY that was so outstanding and amazing, that it would send other games running in panic.
"I came to think that it might be a mistake just to deliver the master version we have finished to everyone. So I realized that if we were to go ahead and release it, then myself and my team would wind up regretting it."
Hajime Tabata concluded: "The disc that is going on sale on the 29th of November, will contain everything that was scheduled to be on the day one patch, as well as some extra things on top of that."
Final Fantasy 15 will now release globally on November 29, two months later than its originally planned September 30 date, Square Enix has announced.
The two month delay is to allow the development team time to "further polish and conduct quality testing so that the reality of the game can match the expectations of both the fans and the creative teams".
"From the moment we joined this project, our vision was to create a level of freedom and realism previously unseen in the series. Regrettably, we need a little bit more time to deliver on this vision and are confident that this new release date will help us achieve this," said Tabata. "As the director and lead of this project, I wish to personally apologise for the additional wait. As a team, we want Final Fantasy 15 to achieve a level of perfection that our fans deserve. We kindly ask for your understanding."
