Second Life - a 3D virtual game

Second life is a 3D world for individuals who want to create a second life by creating avatars and playing them in the 3D world. Second life consists of building houses, buying land and everything that occurs to everyday lives except you interact online instead of real life scenarios. Today, Second Life has attracted businesses that are interested in targeting people through the virtual game by testing their products with customers through the virtual game. Many of Second Life residents buy products in which they cant have in real life or don't want to worry about financial issues. Do you think that this is a good strategy for businesses with keeping in mind that people buy on Second Life due to that they cant afford it in real life. Do you think it would miscalculate predictions on how many products they can sell?
