According to Bethesda executive Pete Hines, speaking in an OXM interview published on GamesRadar, you can sort of thank Fallout 4 for Skyrim Special Edition.
Skyrim Special Edition has been very well-received, were you interpret that phrase as “most of us fell right back down that rabbit hole again”.
Skyrim Special Edition is an unusual for release for a publisher always looking to the future.
Still, don’t expect many more of these (sorry, Morrowind fans; The Elder Scrolls Online is your best bet for now).
