if you ever really get bored, or youve done everything up to the point its all side quests, this is my suggestion/challenge to you:

self induce hardcoe mode

NEVER fast travel ( unless by carriage.)

NEVER wait more than 2 hours. ( sleep in inns)

play on expert and leave it on expert

these 3 simple things will make the game more intense beyond anything youve tried already.

ive been doing it with my lvl 50 nord and honestly, i was ready to gamestop skyrim at the time. but now that ive induced hardcoe mode, the game is " new game" fun again.

I already do that. I am seriously considering disallowing the improvement of weapons and armor as well.
