Finally finished the main quest line...absolutely brilliant storytelling (far better than Oblivion...which I also played forever). Between the soundtrack, visuals and storyline, it was very satisfying.
Playing on expert level. My dark elf is now level 55, dual wielding daedric swords at180 each plus dual enchantments, Nightingale Armor to legendary status, and a Daedric, soul absorbing bow named, The Grimm, that does 180 plus shock. There's not a whole lot that gives me pause anymore, and if there is, I just "shout" and slow time, so i can hack the opponent to pieces. Not many challenges anymore, but hey, I earned this. However, it is still a significant upgrade to Oblivion where I could be level 75 and get killed by a random bandit who just happened to have better gear than me!!! Just need to finish the Stormcloak/Imperial storyline. I figure I'll do that, then roam around a bit for random events, then retire the character until some DLC is released. Possibly run through as a Mage on Master difficulty until ME 3 or Max Payne 3 comes out....either way...fastest 100 hours of my life.
Ton's of moments that made me stop, think, watch, etc....bugs, problems notwithstanding.....loved EVERY minute of it.
