This version of Skyrim is needed to maintain access to the original version of Skyrim, as released. The fact that it has lower system requirements allows it to be played on most any old PC that was equipped for gaming from 15 years ago, that you might have laying around somewhere. Which means it would run on anything recent with integrated graphics chips that are halfway decent. That would be a boon for many people. And I had to get a potato up and running recently after another PC died, and I would love access to the original game without the bloat of steam running in the background, none of that DRM nightmare, please.
