Interesting Game Idea

I have a game idea that I think would be really interesting.  I've recently become interested in learning about how the stock market works and think a game teaching how to trade stocks would be helpful.  I would venture to say that there are others like me who would like to learn trading stocks in a game before getting out there and trying the real thing.  It would take a lot of research to get the feel of the stock market for a game.  A research page showing how stocks change from day to day helping people decide which ones to buy would be a great feature for the game.  So far I have learned everything I know about how stocks work from reading information on websites like scottrade.com.  I think it would be a great game for anyone starting out in a finance class in high school all the way up to people just wanting to make a little extra money.  If you have any feedback or ideas of features that would be great for this game please feel free to let me know.
