Check out Enderal if you haven't already.
It's a total conversion mod, but it's in the steam store (free) as a standalone game.
Playing Enderal is the closest you'll get to reliving your first play of Skyrim, when you didn't know every quest, character, and draugr hole like the back of your hand.
Fair warning: combat is completely revamped, and OP builds in Skyrim like the sneaky archer will get you steamrolled in Enderal.
