The German company SureAI is dedicated to non-commercial game developement, and has been making these total conversion mods of Betheda games since 2005 with Morrowind. The core engine and assets of Skyrim are there, but the world, the story, and even the RPG systems are all completely different. Instead of replacing dragons with Randy Savage, or adding in a player castle to the game, this mod changes everything. Are you familiar with Enderal? It’s a mod for Skyrim, but it’s not your ordinary mod.
