Online worlds are becoming more popular than ever. Many people have belonged to these online worlds for years. Inside these imaginary worlds, video gamers develop characters over time.

These characters learn skills, fight battles, build relationships, and even own property. Some communities inside these online worlds have several hundred thousand citizens!

The people role-playing in online worlds buy and sell things with virtual money. Many gamers earn virtual money by running successful tailor shops and weapons dealerships in their online worlds. Money and treasures can also be taken from victims in battle it’s a dangerous virtual world out there!

But gaining virtual wealth can be too time-consuming for the gamer who wants to buy his castle now. Serious game addicts have begun doing something the online world designers probably never imagined.

Some gamers are exchanging real-world money to buy virtual money and property for their online worlds. Using online auction sites such as eBay.com, gamers buy and sell whatever they need. A whole mini-economy has grown around this trade of goods.

Some of the most valuable items for sale in online worlds aren’t cheap. Sometimes they are rare, which makes them even more valuable. For example, consider a nice virtual house in a prime location. This property might cost as much as a new TV set in the real world!

For the person who doesn’t participate in these online worlds, the appeal must seem peculiar. What’s the attraction with these online worlds？ Why would people spend money on something that doesn’t really exist？

The money being exchanged for those online swords and castles is real. The swords and castles aren’t. Absurd？ Maybe. But the time and effort spent by the players is real. So is their love for online worlds. It seems only the human imagination can make something out of nothing!
