Has anyone played the Evil Mansion mod on Skyrim? It adds a mansion into the game that is a pretty faithful recreation of the original Arklay Mansion, with a Dormitory and Lab area. While it does take liberties due to Skyrim's assets, it was pretty fun to go through it, especially with a gun mod I had. It also comes with great npcs, such as Leonardus and Joanna Valentyne. It has maps, keys, Cerberus, Hunters, and a Tyrant at the end. The only thing I thought was a little weird was that you fight living humans throughout the space, but it was alright. 8.5/10, would recommend.
