I agree. Especially with dungeons. In Fallout, there were places like the museum, they made the world feel real and alive. That's what were supposed to have in Skyrim. I remember once, Todd Howard said something about the hundreds of hand-crafted dungeons. Ha. What a joke. Even oblivion had better dungeons than skyrim does. They're all alike. I think a big part of it is the designe style. It's pretty much all nordic ruins or caves. That gets really old really fast. I actually can't think of any dungeon types besides those two. In oblivion, at least we had alyeid ruins, caves and strongholds.
Hmm let's see. DWEMER ruins. That should be enough, but let's continue. Forts, nordic ruins, caves, mines, dwemer ruins, snow cave, glacial cave, falmer cave, grotos, etc. Not to mention the outside areas, like outside forts, forsworn camps, stormcloak/imperial camps, giant camps, and more.
