The Civilizations

Each of the 18 civilizations in the game starts with two technologies and possesses a unique unit. In addition, each empire has one or two leaders, each of which provides special bonuses. (You get one or the other if there are two to choose between, of course.) Each leader also has a preferred civic that dictates how they like to govern their people. That type of information is very useful when negotiating with other leaders during the game.

Leader Traits Explained
Civics Explained
There are 25 civics in the game, covering the government, legal, labor, economy, and religion categories. You can decide which of the five choices you want under each category, but be prepared for one turn of anarchy in your cities after you implement a change. The following is an explanation of the civics preferred by various civilization leaders; obviously, there are more civics available in the game.
Six Ways to Win
Not every game session has to end in all-out bloody warfare, as you can see below. During the game, you can check the victory conditions screen to see how close you are to the winning the various scenarios compared to your competitors’ efforts.
Mod it Up

“We also learned from Civ III that the mod community for these games gets bigger all the time,” explains Caudill. “Clearly, being able to mod Civ is very important to our community, so we decided to make Civ IV the most moddable version of Civ ever. We spent quite a bit of time creating modding tools that have been widely used by fans and our own internal developers.”

The easiest way to change Civ IV is to press the Escape key while playing the game and select “Enter WorldBuilder,” which will allow you to modify the map with units, buildings, and technologies belonging to any civilization in any era. It’s a fun way to turn the tables on your AI opponents by, for example, massing Panzer tanks on his border and going on a blitzkrieg when he has nothing but archers defending his cities.

You can also save those changes and send the map to a friend or make it available at a website such as Civilization Fanatics, where you can discuss the game with other players and dig through piles of resources. You can also download maps and other content created by fellow gamers for your amusement.

If you really want to tweak the game and you’re comfortable with the technologies involved, Civilization IV also features support for changes made via XML or Python. More in-depth information about modding the game can be found in the Civilization Fanatics archives.
