Comparative Advantage

I haven't posted in quite some time due to mid-terms, but now that I actually have some time, I am able to express my opinion on the main concept of this game: Comparative advantage. I have realized that it is not intelligent to construct the same building in every city of your civilization (such as a colosseum(culture) or a laboratory(science)). Instead, one ought to focus on developping a culture capital, a capital of technology, and a capital of military within different cities. When you focus on one thing (such as military), it will not take as long in that city to produce a modern armor or a stealth bomber. However, if you were to try to maintain a strong balance of military, culture, and technology within the same city, every single aspect would take much longer. If you simply specialize in the production of one thing, your production speed would increase significantly. It is similar to the example given in class between Muffinstan and Baconia. Each country had its comparative advantage, and therefore, was able to produce more of one thing than another. Say you have 5 main cities within your civilization. One ought to specialize in military, one in technology, one in culture, one in the concept of the economy, and another in science or education. The opportunity cost will become much more favorable as a whole. Say you need to produce a granary. Would you prefer to take 75 turns in order to produce one in your military capital or would you prefer to take 2 turns in producing it in your capital of economic production? Easy decision. This is exactly what should be done in Civ IV, and then, it is imperative that you construct railroads and roads in order to trade within your cities (and we know how that allows one's PPC to improve overall). So rather than trying to balance all the aspects of the game within each city, simply specialize in one aspect in each city. Your production speed will increase, and you will be able to establish a dominant civilization. Then, when you are able to trade and become a more developed civilization, you will become as dominant as I am in this game.
