So,it's not a problem that Ald'ruhn style buildings are missing,it's a problem that the design approach has changed.That's how I see it.
I agree for the most part, but you have to allow for the possibility that Cyrodiil or Skyrim were actually envisioned as basically terrestrial. I wont say that's better, but there's definitely some silver lining there. It creates a nice aesthetic contrast between the real and the unreal, and it provides a believable cushion for the unbelievable phenomenon (trolls etc). All I'm saying is I dont think you should knock the artists for putting pine trees in a place where they're supposed to be putting pine trees.
I liked Morrowind more, but that had more to do with the fact that it seemed more concerned with what you could do than how good it looked letting you do that. Oblivion felt too showy, too shallow. Felt like a lot of dolls trying to be human, and morrowind was more a collection of action figures. More fun for me. And I completely agree that all the failure was very encouraging.
