Mods add a bit of new life to the game, but not enough for me to personally spend too much more time in the world of Skyrim. So now that I've clocked ~180 hrs into the game, I feel that there's really not much more I can do with it.
The worst part is that now that I can't get my daily fix of the Elder Scrolls, I'm having TES withdrawal symptoms. Urk.
You burned out after only 180 hours? I've got 350 in, and my main char hasn't even finished exploring everywhere yet, and i doubt I've completed even half of all the quests there are. Haven't even picked a side yet, in the war. You must have missed an awful lot of stuff along the way.
