The first time I saw a virtual world game was Second life Since then I realized that this kind of games will have a real effect on the real world, I have been playing this game every now and then from about a year and a half ago.
People started to realize the power of the virtual community and that it is an international new market, people in Second Life create virtual objects and advertise for it to sell it for Linden Dollars or even advertise for real products. I have seen people creating objects like clothes, furniture & cars to sell them I even have seen an apple store that sells apple products.
In the last days I saw people collecting donations for Hurricane Katrina relief effort. Linden Dollar is the currency of the game can be exchanged with real Dollars and vice versa.
