If you have a few minutes, read this fascinating article about virtual gaming and economics. A down-on-his-luck economics professor started virtual gaming at his home and began looking into the economy of the gaming world. When he realized that virtual goods and currency were actually being sold at online auction sites, he took notice:

He began calculating frantically. He gathered data on 616 auctions, observing how much each item sold for in U.S. dollars. When he averaged the results, he was stunned to discover that the EverQuest platinum piece was worth about one cent U.S. — higher than the Japanese yen or the Italian lira. With that information, he could figure out how fast the EverQuest economy was growing. Since players were killing monsters or skinning bunnies every day, they were, in effect, creating wealth. Crunching more numbers, Castronova found that the average player was generating 319 platinum pieces each hour he or she was in the game — the equivalent of $3.42 (U.S.) per hour. "That's higher than the minimum wage in most countries," he marvelled.

Then he performed one final analysis: The Gross National Product of EverQuest, measured by how much wealth all the players together created in a single year inside the game. It turned out to be $2,266 U.S. per capita. By World Bank rankings, that made EverQuest richer than India, Bulgaria, or China, and nearly as wealthy as Russia.

It was the seventy-seventh richest country in the world. And it didn't even exist.

Castronova sat back in his chair in his cramped home office, and the weird enormity of his findings dawned on him. Many economists define their careers by studying a country. He had discovered one.

Or perhaps you are a tad religious? How about virtual church service?
