Problem is, it's an even further decline from Oblivion in the character development and customization part, which is easily one of the most important areas of open-world games.
Nah, give me Daggerfall character creation, give me spell creation and all the spell effects back(and many more), give me levitation, M&R and transit points and lose the fast travel, give me Daggerfall item enchantment back, give me character attributes back and a proper skill system, place non-scaled and interesting unique items in special locations, give me open-world cities again, lose the goddamned quest compass and give proper quest dialog, give me large buildings and abandoned castles to explore, etc. At that point we can start talking about incline.
As it is, Skyrim's just an even more dumbed down TES game which manages to slightly surpass Oblivion solely because of better art direction, fancier-looking combat and less obvious level scaling. But those were just a few of the problems with Oblivion, the rest of the game also sucked and that still hasn't changed.
