“Economics is loosely defined as choice under scarcity. After all, in the real world, there’s only so much to go around. You can’t always get what you want, and unfulfilled desires give rise to markets. But in a game world, there’s no inherent reason for scarcity. Game designers have given us plenty of utopias where we can have all the mithril we want, to buy whatever we want whenever we want it. Problem is, those worlds turn out to be dull.”
