. . . Actual population numbers, each head representing so many people. As technology progresses the ratio of people represented by the heads increase. As well the ratio of food to food icons. Land will produce more, with better technology, but people will need to eat the same. . . . Population growth would be based on the numbers, not the heads. For example, starting default well fed population growth per 10 years could be 20 percent. Latter on better technology (longer life etc) will cause increase growth rate. (even as turns passed equal less years) . . . Fighting units, etc would come from the people, would require population and food support accordingly. . . . Well if anyone has any better ideas I'm all ears, but man I hope its not the same population system of food = people. Anyone know of they have something a little smarter in mind for civ4? Even a pop from 2 every 5 turns (everyone needing to eat 2) would be a improvement.
