I really like the cave graphics, but was hoping for more diversity. I've been in about 20 of them now, and I am ready for a change. Is it possible that DLC will include new types of dungeons? Everything is a ruined burial site, filled with dragurs. Maybe we can explore a castle, or a tomb, or ... really anything else.

Well, I gotta say it seems more diverse than Oblivion's dungeons.

there's castles, tombs and dozens of other cave like structures
you just see a lot of ancient nord architecture in ruins because that was the dominant culture in skyrim
has to be a certain sense of consistency
I quite like the diversity of dungeons actually, nothing wrong with it

The caves are actually quite varried between snowy cavern, wooded animal lairs, burial sites, and the like. This is of course excluding the truly awesome dwemer ruins and forts.
