It would be satisfying for people like me who adhere to the philosophy of Ahimsa (do no harm), if there were an add-on or something that would allow the player to fight against evil (similar to Knights of the Nine).
I know some will say, "Why do you play this game if you don't like the violence?" To which I would reply, there are no other games with such scope and flexibility, such a variety of choices and such a beautifully rendered environment. The sheer open-endedness makes it unique and well-worth forking out $40. I would just like an opportunity to do something that makes my character feel good about herself, proud to be a hero, rather that a mass killer or lawbreaker.
I used to love the Myst series and other adventure games where you made progress by solving long, difficult puzzles, but there aren't many of those published today.
Don't get me wrong, I love TES games, but I find them becoming a bit one-sided.
