Skyrim and Dark Souls came out roughly around the same time. I remember it well. There wasn't a rivalry between the two games but I do remember that a lot of players felt as though Skyrim was taking attention away from the superior fantasy-themed RPG.
But imagine if they were one and the same?
That's sorta what this Skyrim mod is about -- but it's more like a very real attempt to make Dark Souls work within Skyrim itself.
It's actually pretty successful. Actually, more like the video does a great job, with its editing and the overall aesthetic, or creating a Soul-esque atmosphere within Skyrim. It looks fantastic.
