SELL!
          Sell! is 
            a multi-player real-time simulation, networked game that teaches basic 
            marketing and microeconomic concepts. Players are immersed in a simulated 
            environment where they are expected to save a failing retail outlet.  
            The game is set in the virtual town of Springfield.  The players 
            are responsible for buying merchandize, setting prices, advertising, 
            hiring employes, etc.  If the player does their job well the 
            town's ecomomic simulation will "buy" from them, and not 
            from their competitors.
          The ILS 
            Sell game was implemented with a Unix-based Sell Server and a Macintosh-based 
            graphical client program. After using the client program to connect 
            to the Sell Server, you would see the main window of the game. It 
            consisted of two major sections, the top part is the MOOPort and the 
            bottom is the dashboard. To see the interface and a more in-depth explaination
