And I have an RPG, Nobilis, which is absolutely gorgeous and which has background and rules to play a a god or goddess of something. And I think of the tales that could be woven: either sweet children's fairy-tales, or Barkeresque dark tales of a war just below the surface of reality. Or, quite possibly, an odd mix of the two.
And then I think of the work and time involved in preparing for a session of Rolemaster -- which is a quite standard fantasy RPG. There is no way I could justify the investment in time to get this off the ground, unless every player get their hands on the book first.
