Sales of Metal Gear Solid 4: Guns of the Patriots (PS3) as reported by NPD here do not include copies bundled with the PS3 hardware.

Neither Grand Theft Auto IV (Xbox 360) nor Grand Theft Auto IV (PS3) made the Top 10 this month and so we will need to get the data from NPD manually. There may be some delay due to E3.

How exactly does this work?

Gamers and developers sign up on the simExchange for a free trading account. Using virtual currency called DKP, players buy virtual futures contracts that are under-predicting sales and short sell futures that are over-predicting sales. This concept is widely known as "the Wisdom of the Crowd" and this system is known as a "prediction market."

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).

The following are upcoming GLS Stock IPOs. Remember, each stock enters a 48-hour IPO Phase 1 in which there is no market maker providing prices. Advanced trading mode is required to place orders in IPO Phase 1. After IPO Phase 1, the futures contracts will enter IPO Phase 2 in which the bid and ask prices will be fixed all day. Most GLS Stocks will also have an accompanying Metacritic Future.

If you want a game listed for trading, be sure to bid for it in the Unlisted Games section.
