We're planning on including quite a few moral dilemma's in our next game, forcing the player to make choices that have consequences on the inhabitants of the world as well as him/herself. In a lot of cases the consequences aren't immediately clear as it takes some time before the ramifications of a particular choice propagate. This can be an issue, and one way of solving that would be to give you a hint of what will happen if you make a particular choice. I'd be very interested to hear your thoughts on that.

I think moral dilemmas where the choices you make affect the way the game plays out is what separates a good RPG from a good RPG. You are role playing to larger degree.
