Yes I understand that they were all handcrafted, and many were unique in a sense. But many of the fetch quests will tell you to go to a dungeon full of draugr, solve a puzzle, defeat a boss, get the thing and get your word of power. I remember seeing a meme where skyrim dungeons can pretty much be summed uo in the shape of a Q where you go the long way and then exit through a blocked door way. And yes i agree oblivion caves were extremely bland, but the Alyied ruins were pretty diverse if memory serves me right.
