90% of Skyrims dungeons are a straight A-B affair and offer no exploration whatsoever. This is not good. Its painfully obvious that each of Skyrims dungeons were designed to cater to the player, with nothing but a long corridor (did someone say COD meets fantasy?) with a loot chest at the end. Compare to Dark Souls 2, with dungeons that have various passages and routes the moment you enter... they actually feel like real locations that you have stumbled upon rather than the tour bus style of Skyrims dungeon design.
Bethesda are masters of open world exploration, but they need to work on their dungeon design. Its too bad because they got the mini-stories spot on. But I want to explore as much as read about some mage who went looking for his kidnapped wife.
