A review in the FT Magazine of Edward Castronova’s Synthetic Worlds, a book on online gaming, asks
“when will synthetic worlds become economies worth reckoning with? They are already real, and are the fastest growing economies in the world. But they are small: all the synthetic economies put together, with about ten milion players, are about the size of Bosnia and Herzegovina.”
But I don’t think of Bosnia and Herzegovina as small. I remember a country that took a day to cross on bad roads, where hundreds of thousands of people grew enough food to eat.
