What FRPGs can teach us about gold

"Look at games like World of Warcraft, Diablo, Dungeons and Dragons, or the original Final Fantasy. In those games, gold is the money, and you often get gold not by doing an honest day's work, but by running around and beating people up and taking their gold. In other words, the entire world of modern fantasy role-playing is a subtle joke on gold's unsuitability as a medium of exchange." -Noah Smith (via Making Light)
