Skyblivion update for Skyrim.
Skyblivion update for Skyrim.
They believe having Skyrim and Oblivion with all DLCs is necessary for the mod to function. Whether Skyrim needs a special edition or not depends on the specific mod you're using.
It depends on whether the module is 64-bit or 32-bit; for 32-bit versions it functions on both platforms, while 64-bit versions are limited to specific systems.
