CNet has a good follow up to the story gamesblog posted last year, in which an everyday Joe forked out $26,000 for virtual land in the online game Project Entropia. From the article:
"Storey said he's making a modest income from the property now, collecting small payments for hunting rights and other fees. But he expects his investment to really pay off once MindArk releases a housing update for the game and his virtual bulldozers start digging out prime home sites fellow players will pay to occupy."
The article gives a great overview for the curious and uninitiated to the wierd world of the economies of online games.
