Hello.
I've played Skyrim a fairly noticeable amount of hours (940+), split in 3 classes: pure mage, pure warrior, warmage.
I've never reached lvl 81, even after exploring almost every dungeon and completing all the quests except the Dark Brotherhood, Namira, Hircine and boethia cult. My actual max level is 59, and my problem is that I hardly find anything to do, except fooling around in Skyrim and Solstheim just to beat never ending dragons and assorted enemies. After my first char I simply started a new class, to play through the same stories again.
My question is: What's beyond the main quests and side quests? How it is possible to go on with a class after beating almost every mission of the game? How can I reach lvl 81? are the some new procedural missions or quests generated by the game?
