I am creating a "Modern Earth" scenario for Civ IV. Over 5000 units need to placed on the map. However, I must first create the new map and need to place and populate over 700 significant cities. Then need to improve the terrain surrounding the cities. I must also set the starting tech levels for each civilization; 40 in total - Lesser nations have been combined into groups like , European Union, Arab League, African Union, Latin America, etc.
