A long time ago. Final fantasy III came out with a new approach to learing magic. The characters would be equipped with espers(magical beings) and as they fought more battles, they would learn spells from the espers. What if a similar approach to learning magic was applied to a P&P rpg?
Atheists and agnostics get a jolt when one or more deities make an appearance, and take a direct interest in things. It is hard to deny the existence of gods when one has met them face to face.
