Where do the expected sales numbers come from?
The simExchange is the video game stock market. Gamers and developers sign up on the simExchange for a free trading account. Using fantasy money, players buy virtual stocks in video games they believe are under-predicting sales and short sell stocks they believe are over-predicting sales. This concept is widely known as "the Wisdom of the Crowd" and this system is known as a "prediction market." Sign up and play today.
About the predictions
Predictions on the simExchange should become more accurate over time as (1) the diversity of the pool of traders increases and as (2) more accurate players are rewarded with more virtual currency for their accuracy (thereby enabling them to form more predictions) and less accurate players lose virtual currency (thereby discounting their ability to form more predictions).
