Entropia Universe is a massively multiplayer online virtual universe designed by the Swedish software company MindArk, based in Gothenburg.
Entropia uses a micropayment business model, in which players may buy in-game currency (PED - Project Entropia Dollars) with real money that can be redeemed back into U.S. dollars at a fixed exchange rate of 10:1. This means that virtual items acquired within Entropia Universe have a real cash value, and a participant may, at any time, initiate a withdrawal of their accumulated PED back into U.S. dollars according to the fixed exchange rate, minus transaction fees; the minimum amount for a withdrawal is 1,000 PED. The Entropia Universe is a direct continuation of Project Entropia.
Entropia Universe entered the Guinness World Records Book in both 2004 and 2008 for the most expensive virtual world objects ever sold. In 2009, a virtual space station, a popular destination, sold for $330,000.[1] This was then eclipsed in November 2010 when Jon Jacobs sold a club named "Club Neverdie" for $635,000; this property was sold in chunks, with the largest sold for $335,000.[2][3]
Also of note: in 2014 Planet Arkadia started selling 200,000 Arkadia Underground Deeds (AUD) valued at $5.00 USD each (50PED) making the Arkadia Underground valued at $1 million
