Adds stuff that it doesnt explain.... but still good of course

But its still civilization 4 and plays the same. the only things it adds is espionage (i could read the civilopedia on how to use it but id rather be on my next turn) some new units and i think more factions and leaders. New units include spies (both modern and ancient) anti tank infantry and more. bulidings have also been tweeked so that some give out a espionage rate (kind of like a resource like gold or science) and the Apolistic palace has been added and its like a UN buliding for a certain religion that the owner has. As far as i know the AI hasnt really changed in this expansion so if your looking for more of a challenge( don't know why i can barely win on cheiftan difficulty) then your better of playing a human oppenent. overall its still bloody addictive and can keep you up till the break of dawn.
