Dungeons aren't exactly this game's strong point for me, they're incredibly repetitive, same enemies, same layout, with the odd fisher-price level puzzles of turning animal stones around to unlock a door. Dwemer ruins are depressing - oh look, robot things. Wonder if we're going to get to a really deep part and meet falmer and chaurus - oh, there they are. Wasn't expecting to see them down here. Now I just need to find the centurion so i can get this over and done with.
I do enjoy Potema's tomb, though. I like the way it starts off as just an old, abandoned part of the temple tucked away underneath the city, with waterways going through it, to a musty ancient tomb filled with draugr, and I like the bit at the end with all the magical energy, that was awesome.
And the dungeon you go through to to get the Dawn breaker - I was astonished by how different that place was, with all those shadowy things creeping around, I was like "F-me, new enemies?" thought I had wandered into a different video game. And getting the light to flow throw all the hallways was fun as well.
