Just a heads up to check out the CivIII FAQ new info. Some VERY interesting stuff there:

Just for convenience, here is the list of FAQ updates from civfanatics:
System requirement change: 400 MB free hard drive space instead of 100 MB.
When you are at war with another Civ, your embassy in their capitol is automatically closed, and you will be unable to investigate city or steal technology. However, you can still conduct other espionage missions (sabotage, propaganda, steal world map, steal plans, expose enemy spy) as long as your spy is not caught.
Conscripted units have only 2 hit points. Conscript units can be received when exploring barbarian villages ("Goody huts"), and are also produced when you use the draft to produce soldiers.
Drafting: Once your Civ has discovered Nationalism, the draft becomes available. Drafting citizens effectively converts a population point into a military unit. Depending on your level of scientific development, that unit will range from a Spearman to an Infantryman. Government types directly affect how many citizens from each city can be drafted per turn; Republic and Democracy can draft 1 citizen per turn, while Depotism, Monarchy, and Communism can draft 2 citizens per turn. Civilizations in Anarchy cannot draft citizens. Drafting is very unpopular with your citizens, and each use of the draft will make one citizen in your city unhappy for twenty turns.
The "Dan Quayle" screen of the original Civilization is back. After winning, losing, or retiring from a game, you will be ranked and given an appropriate title that suits your accomplishments.
Only ground, non-artillery combat units may join an army.
The effect of Mobilization is changed. Instead of halving the maintenance cost of military improvements and doubling the maintenance cost of non-military improvements, mobilization now allows all cities building a military unit to produce one extra shield in every square that is already producing at least one. A mobilized Civ may only build military units and military city improvements, and may not build peacetime improvements.
