Gamer makes a cool half-million by selling virtual property

Think the rent is, in fact, too damn high? Then stay as far away from online world Entropia Universe as possible, because its real estate prices will drive you insane.

Take, for instance, what just went down on Planet Calypso, where one of Entropia's wealthier players has sold off his interests in a "resort asteroid" for an eye-popping $635,000.

The seller is Jon Jacobs, also known as the character 'Neverdie'. He originally purchased the asteroid in 2005 -- eventually converting it into the extravagant resort 'Club Neverdie' -- for the then-record price of $100,000. For those keeping score, that's a gain of over $500,000 in just five years. In nerdier terms, that's an ROI of 535%. Match that, Citibank.
