Morrowind is the height of the series for me and one of my favorite games of all time. But the level of detail and fidelity in Daggerfall is just staggering.
Cloudpunk - A cyberpunk driving/walking simulator with a good story, great voice acting, LEGO-inspired graphics, and a Blade Runner inspired soundtrack. It’s dripping with atmosphere and I wish I could play it again for the first time.
Any town with a wall around it in Oblivion is instanced.
Also, you have correctly recognized Morrowind’s superiority. I highly recommend the Tamriel Rebuilt mod that adds a lot of the land mass of the rest of the province outside of the island of Vvardenfell!
