I have to play Arena... If they create that dugneon on TES1, on TESV they have to recreate something.

I would like to see believable 10-20 level dungeons hewn out of the rock; Preferably with large areas that are not easily found, and with (perhaps) some interesting & unexpected exit points.
It would also be nice if there were certain puzzles guarding them, where the answers are generated at run-time ~and so... unique to the savegame of the specific PC.
