There’s Skyrim plus the three DLCs, Dragonborn, Dawnguard and the shitty house-building DLC no one cares about. The base version of Skyrim alone, Skyrim Legendary Edition and Special Edition.
Skyrim Legendary Edition and Skyrim Special Edition. On PC however, there are two versions of Skyrim to choose from. It’s on the Switch, it’s on PS4 and XBox, it’s everywhere. There are so many versions of TESV: Skyrim available right now.
