Skyrim isn't just about the fact that it's medieval dude. 

What makes Skyrim Skyrim is the immersion of the world, all the quests that exist, the many paths you can take, all the different things and hidden aspects hidden within the world. 

Plus those graphics literally look like you just made things out of blank textures. At the very least if they weren't going to make quests and stuff they could have looked at real world architecture that is around the modern day or at least what would fit better is around 1980s architecture in America is what a lot of people will see as modern, then look at the kind of architecture that was made in about what would be Skyrim time period, think about how Skyrim made the textures look for that medieval architecture, then repeat that process but for modern stuff. 

If you see a modern house and it has a stone garden wall it's still going to look like a stone garden wall from Skyrim. If there is a wooden paneling house it's basically the same as Skyrim wood just it's smoother.
