In class we have been talking a lot about comparative advantage, and how it is in your interest to utilize your advantage. In CIV IV each leader has a special skill set. The Americans (my favorite) have special units and starting technologies. The American special unit is the navy SEAL; no other CIV can produce a SEAL. The unit itself is great, it has all the advantages of any other foot soldier (it can climb mountains) and it does more damage to opposing units. To gain access to this unit your civilization must be advanced, so it is in your best interest to progress through the ages as fast as you can. Early confrontation gives you no advantage; actually it puts you at a disadvantage because most other civilizations have special units that come earlier in the game. Diplomacy is a must to maintain peace until you have the upper hand.
Although the units are important in this game the other attributes are arguably more important. The Indian empire’s workers are able to build faster than any other civilizations. The American cottages produce more gold per turn than anyone else. So as I learned in class, I used my advantage by building an extensive cottage system and used the gold generated to buy other necessities that were in low supply.
