All editions offer more or less the same, although in the case of the PC version Bethesda decided to reward old fans.
The Elder Scrolls V: Skyrim Special Edition was also released on Xbox One and PlayStation 4. Of course, all this is complemented by mods, which became famous for the 'base', which is one of the most modified productions in history. The developers took care of such things as higher quality textures and effects, volumetric lighting and dynamic depth of field. The production is designed for personal computers and offers all expansions released for the original (Dragonborn, Dawnguard, Hearthfire) and a number of graphical improvements. The Elder Scrolls V: Skyrim Special Edition is a remastered version of the game The Elder Scrolls V: Skyrim from 2011.
