I can force someone into folowing laws,
or I can try to ignite the conscience in someone.
Of course. I didnt mean that you have "to force" someone to understand. There are more ways of learning and education. Some may be slight but have strong effect. Yes, ignite the conscience is the way.
I am pleased that you mentioned Ultima and virtues. Ultima series (Ultima Underworld) is one of my all time favourites. And system of virtues is perfect example of the thing I wrote about in previous post (that "educational value" that doesnt look educational at all). I seemed so interesting and deep to me (years ago when I played the game) that I had to think about the world and what means to be hero to inspire people, not just killer of monsters - and what is the "way to be avatar".
