Bethesda is blaming Sony for preventing them from adding mod support to the PlayStation 4 versions of Skyrim and Fallout 4.
In an open letter to the fans, Bethesda said:
"After months of discussion with Sony, we regret to say that while we have long been ready to offer mod support on PlayStation 4, Sony has informed us they will not approve user mods the way they should work: where users can do anything they want for either Fallout 4 or Skyrim Special Edition.
Like you, we are disappointed by Sony’s decision given the considerable time and effort we have put into this project, and the amount of time our fans have waited for mod support to arrive. We consider this an important initiative and we hope to find other ways user mods can be available for our PlayStation audience. However, until Sony will allow us to offer proper mod support for PS4, that content for Fallout 4 and Skyrim on PlayStation 4 will not be available."
While Sony's decision is disappointing, it is not really unexpected. Console platforms owners have always been against giving users the ability to share user-created content in order to avoid exposing their younger users to unregulated content.
