Well, I finished the main quest. It was okay, but nothing special. End boss was pathetic, I just pressed and held the left mouse button to unleash Lightning Storm and that was that.
I killed 30 dragons in total, the majority of those on mountain tops (never experienced any dragon "cliffracer" syndrom other people appear to have), still need to kill 14 to master all shouts.
So far I say College of Winterhold > Thieves Guild > Daedric quests > Main quest > Companions.
