I'm approaching some game development companies with the idea of developing a 3-D world game evironment for trading. It can be in simulation mode or broker linked mode. Initially you will see a rotating globe with the current exchanges/markets offered in different countries that your broker allows you to trade. The globe will have real time daylight-nightime cycle. Once you zero in on the exchange or futures product you want to trade, you enter into 3D representation of the exchange with accurate floor models and pit locations. If your trading the SP 500 you will see other players/traders that are trading that in that pit represented as 3D characters. Market depth will be represented as simulated floor brokers. So in the 3D environment you will be able to see the market represented in a more realistic form. You will be able to chat using audio with other traders. As more exchanges come online it will simulate the trading world in general. As a novice you will be able to practice, and then switch over to real mode when you think you have honed your skills. What kind of market do you think there would be for this?
