Mindark, 2003

In 2003 Swedish software company MindArk launched Entropia Universe: a MMORPG with a planetary system and a real cash economy. Entropia Universe entered the Guinness World Records book in both 2004 and 2008 for the most expensive virtual world objects ever sold. It reached another milestone in 2010 when a virtual resort on Planet Calypso was sold for $635,000. Real dollars, that is. And just when the developers thought it couldn’t possibly get any better, the Entropia Universe reached yet another major milestone: a place in the Big Internet Museum.
