After 105 hours, and finishing the main quest, imperial quests, and being the thane of falkreath&winterhold&solitude&whiterun&riften, and the harbringer of the companions, I decided I was finished. I didn't do the quests of windhelm or dark brotherhood, only half of thieves guild and markarth etc. So I decided to make another character and have another go. There were no point in doing ALL with one character, there's so little challenge left when you're lv50.
