Anyone recall a fun skyrim challenge? Like restrictions, builds, etc?

I mean Master or Legendary is obvious a challenge enough in itself but can any recall anything else that was popular?

Hardest difficulty, no armor, no buying any weapons or spells, only use what you find, and no healing potions, only spells, aannddd no using the quest markers (believe there is a mod that removes them). Can't remember what the challenge is called, but saw a guy do it on youtube and have to be VERY skilled to be able to pull it off heh.... theres a couple more rules and restrictions but can't remember them

I'm starting a no-kill play through. A priestess type character.
Only my followers will be able to kill enemies.
No stealing, no lying.
Link in sig.

Only use conjur spells and pickpocket skills, start game on legendaryinstead of adept? ^

play blind-folded.

play a all stamina archer on the hardest difficulty. glass cannon ranged. BUT play it without any sneaking EVER.
