working disguises would be epic. imagine sneaking into a bandit camp dressed as one of those bandits! id also like eating, sleeping, resting, etc, to have more of an affect (not sure how tho). narcotics (ie skooma) would be cool. leading a faction more realistically (assigning tasks, managing facilities, etc).... just some thoughts
I was thinking about this earlier. Dressing up as a Bandit or Forsworn, entering their camp without a problem, and then murdering them as they slept would be fun.
Also, I think linking Stamina to sleeping would be interesting. The longer you went without sleep, the slower your Stamina would regenerate.
