gme s tock is a stockmarket game
If you have more than one player, you have to decide who is going to be the banker or if each person does their own banking when the mouse is free. The only downside to this stock market game is that I forgot the key you enter to stop the game from nagging you every 15 minutes for the key.
With gme s tock, I have forgotten the key and I don't have the source code for the game anymore. The fun thing about the game is that if you have no one to play with, it has a rudimentary artificial intelligence built-in that will give you a run for your money. Till you learn how to play well enough, it is very hard to beat. I beat it sometimes, and I programmed it.
