Square Enix reportedly doesn’t have plans for a Final Fantasy 16 day-one patch.
This comes by way of a Game Informer report, which explains that Square Enix is confident with the current Final Fantasy 16 build. In addition, producer Naoki Yoshida feels that games should work as expected on launch, especially since not everyone has access to the internet needed to download a day-one patch.
That’s not to say Final Fantasy 16 won’t get updates in the future. The game’s director Hiroshi Takai did confirm that the team is currently searching for bugs, so it’s possible Final Fantasy 16 will receive updates after it launches. Once it’s in the hands of players, bugs will probably be discovered.
