I have tried a different approach to Civ III (Conquests). I turned off all victory conditions and went exclusively for a histographic victory. Unfortunately, I started on a small island and it has taken until 2000 to completely control one of 2 continents. The Celts own the other (somewhat larger) continent. The Celts have over 2000 moderm armor and nearly 2000 mech inf. I want to wipe them out in the mother of all wars and decided to invade with a force of about 700 MA 700 MI and 350 Radar Artillery which requires about 300 Transports and some destroyers, AEGIS Cruisers for protection. In short, I have reached about 2700 total units including workers and aircraft and the game will not let me build any more. Oh, it allows me to build them but they immediately disappear. I'm on a huge map and have 111 cities. Is there some algorithm controlling the maximum number of units you can have at one time? And if so, how come the Celts have over 5000 total units?
