The joy of Morrowind was that it was so weird. In some ways very much like an alien world. For me transitioning from silt striders and strangeness to the more generic fantasy environment of Oblivion was a sort of aesthetic whiplash, and one of the reasons Oblivion captured my imagination slightly less than Morrowind.
The Skywind team, which seeks to recreate Morrowind in the Skyrim engine, seems to get that. Their latest video focuses on the Daedric Ruins in Morrowind, one of the weirder things you can come across. Ported into the Skyrim engine, they look quite beautiful, and that essential strangeness is mostly intact.
