I remember 25 to 30 years ago playing a game at my moms work on a IBM computer that was a very simple game but addicting. If I remember right all you were able to do was input a couple of categories and try and build your civilization up. It seemed the time table was monthly on the game and each month you input the same 4 or 5 categories trying to make calculated guesses and see if your population went up or down. If anyone has any input I would appreciate it.
