The Entropia Universe

The Entropia Universe is a virtual world on the Internet, which seems very like our real life．It is set in a distant future and based on a planet called Calypso．Entropia was the brainchild of a group of Swedish computer lovers who decided to see if they could create a three dimensional (维度的) virtual world that could be placed on the Internet．They did manage after they received the financial backing they needed．

    The game can be played for free, but nearly all in-game activities require personal resources that you have available to use．Although there are various activities to keep you busy on Calypso, what most people do first is to find themselves a profession, such as hunting the fierce animals on Calypso, mining the precious minerals and making tools．Then they can think about buying their virtual house or paying a visit to a virtual nightclub or doing any of the other activities that make life bearable．

    Entropia has its very own economy (经济) and its own currency, the PED (Project Entropia Dollars)．Players move real world money into PED which they then use to pay for their life on Calypso．However, the virtual things inside Entropia do have a real value in the outside world, and careful business deals mean that players can actually make real money there．PED can be changed into dollars any time at a rate of 10PED to 1US$．

    What’s so impressive about The Entropia Universe is the number of players; currently more than 600,000 representing over 220 countries from planet Earth．A number of players insist that it’s a good way to make money．However, the reality of Entropia’s economic system is that most people end up paying more than they earn and it’s not uncommon to find players who are paying up to $200 a month into their PED account．This might not be the most economical way of spending one’s free time．However, some people say that for them the fact that they can escape the realities of the earthbound life and become a different person with a completely different life for a few hours every week is worth the use of money, even if they don’t get any interest rates on it．
