To recap: Game Informer is supposed to have pants wetting art on the cover next month. Some people think TES does not do "pants wetting" art.
Well like I said its the quality, and its not just wow. They can have down to earth standard traditional fantasy art and still have it look phenomenal, so they chose not to?
the concepts beth makes may not be fully rendered and epic, but they are great for modeling. when you're modeling something you don't want a fancy pose and realistic rendering and a good composition, you want a simple, clear image which you can import directly into a modeling program. Something likehttp://ericreber.files.wordpress.com/2009/04/09d-138-011.jpg or http://www.worldofwconline.com/gallery/albums/concept-art/ca14.jpg may look cool, but its next to useless for modeling.
Personally, I prefer Oblivion's European-esque style to WoW's "fantasy" style. As I've said several times before, the giant spiky paldrons thing isn't fantastic, its cliche and even more boring than copying Europe.
Personally, I don't mind what Oblivion and Morrowind did. They were not fantastically rendered but they have their own sort of flair. That being said, ArenaNet is my favorite when it comes to concept art. They have a great collection of both functional and atmospheric concepts, and they are always willing to share with fans.
