One way you could get a more role playing aspect into the game would be to have a role playing button that you could click (Along with the difficulty level)
Once clicked the extra role playing options would include making sure that you ate enough feed and slept enough etc. If you do not get enough food, drink or sleep then your combat skills would be reduced and then after a while you would not be able to run due to lack of energy and not being able to fast travel (unless you use one of the carriages at the stables)
I think something like this could be added to an expansion pack.
What do you think?
