I am done after the 40th or so. It's repetitive, always is underground and it seems like the land above has no interesting points to visit. Sure, I will still crawl in forts, buildings and whatnot but I refuse another dungeon crawl, how tempting the loot and design might be, it's not the greatest strength of TES for me.
TES should have had the sub-sub title: Skyrim - Dungeon Crawler. I find it rather offending the beauty of Skyrim's lands is merely used for travelling before you are send to the umpteenth dungeon by the Radiant Story. Do note I love this game, it's just I can't stand the dungeon re-visiting constantly.
Rant is over and please refrain saying I should stop playing or utilize more variety with my gaming, I already do this.
