After all these years the detail into this game never ceases to amaze me. I'm 20 hours with my new Argonian and still on the Thieve;s Quest line. I haven't started any of the DLCs(I have the GOTY edition), nor the fighter's or magic guild quests, or the Arena, or most of the towns.
I still hold to the feeling that you don't beat a Bethesda game, you live a Bethesda game.
