What was your "eureka!" moment in Civ 3? What is the strategy or tip or thing you figured out that most dynamically changed your game and brought you to that next difficulty level or next echeclon of cometitiveness? For me it was two things- the first thing was figuring out that rapid expansion to start is the best way to become dominant, no matter the victory condition. In Civ I and Civ II, and a while in Civ III, I would just have optimal city placement, and get a core of 5 or 6 cities, and just rely on military expansion for the rest. This really stifled my victory ability, and kept my difficulty level at Regent or lower. Once I figured out that starting the game by pumping out settlers/cities as fast as possible, I was able to jump up to Monarch and dabble in Emperor. The second thing was figuring out that the outer cities that are super corrupt can serve a useful purpose- pumping out workers to improve infrastructure, and pump up the city population in the core. This was a game changer, since for so long those outer cities were basically just taking up space and producing nothing. What were your big game changing tips?
