Whenever I plan on ending a playing session... I feel compelled to open up the console and spawn a few hundred frenzied Draugr/Dremora and watching them duke it out in a free-for-all.
It looks something like this: http://cloud-2.steampowered.com/ugc/541831196172416275/98E01C66524987B56DA36A36DD29F5BA2B48C580/
I then keep telling myself: "No more. No more. K... maybe one more..." Sometimes I don't stop until the game can't handle the amount of dead bodies...
