Basically, you get 10K in fake money to "play the stock market". Only in this case, the sotck market is items off Amazon.com.
You buy stock in an item, and if the Amazon Rank of the item goes up, the stock value goes up.
I'm not only in the top 50, I'm actually #11....so I'm doing VERY well for myself.
Now, if Heros of Might and Magic V would just sell, I'd become a multi-millionaire. I have over 4 million shares of that stock presently...
