GOG lists Starfield's release date as June 29, 2023, but this date is oddly specific and a little out there for a couple of reasons. All rumors such as this should be taken with a grain of salt, and while it is possible this is genuinely Starfield's release date, it remains incredibly unlikely.
As many fans know, Microsoft and Bethesda are planning a dedicated deep dive into Starfield sometime in the future, and it stands to reason that its release date would be revealed there. The recent Developer Direct also confirmed a May release date for Redfall, and it has always been tied to Starfield's. Bethesda once stated that Redfall would release first, meaning that June is not an odd guess in the slightest.
Beyond June making sense and known reporters like Jez Corden speculating about a June release date, the thing about Resetera's discovered June 29 date is that it's an odd placeholder, if that's what it's supposed to be for Starfield. Placeholders typically fall onto the last date of a given month or period, meaning that June 30 would be the most likely date used if it was a placeholder. Furthermore, most video games release on Tuesday or Friday, meaning Thursday would be an odd pick at that, but stranger things have certainly happened.
There are some reports that this GOG release date has been up longer than some may have realized, but a few recent tweets about it have this date making the rounds online. Either way, in response, it seems GOG has taken down the June 29 Starfield release date, which could mean anything. While this does fit Starfield's promised first half of 2023 release date, it does so narrowly, and this is despite other rumors suggesting Starfield is being delayed into the second half of 2023. Ultimately, fans should take all of this with a grain of salt, as nothing is certain until Bethesda or Microsoft announce it themselves.
If this is the case, then it means that Starfield will be going head-to-head with Final Fantasy 16. Its release date is June 22, another Thursday as Square Enix often breaks from the typical Tuesday/Friday pattern for a variety of reasons, and this would mean Starfield releases a week later. At the very least, there is some time between the two games, as fans are no strangers to multiple, big games releasing within the same week, if not the same day.
Starfield is in development for PC and Xbox Series X/S.
