Largest online game economy

According to research by Prof. Edward Castronova at Indiana University, USA, in 2005, the Kingdom of Norrath in the game Everquest has a gross national product (GNP) per capita of $2,266 (£1,317). This figure was based on a market-exchange rate between virtual Norrath gold coins sold at an online auction. The GNP category has since been replaced by that of gross national income (GNI). Based on the latest available figures from the World Bank, for 2005, this would make Norrath the world's 125th largest economy, coming after the actual economy of Swaziland, which had a GNI per capita of $2,280 (£1,325).
