Civilization 3 follows the basic pattern of the previous civilization games. Starting just with a single group of settlers in the year 4000 BC, you'll have to explore your world, establish new cities, build civic improvements and great wonders, negotiate with rivals for limited space and resources, wage war against your enemies, research new technologies and generally try to do all you can to stay competitive with the other civilizations while making sure things don't fall apart at home.
Civilization 3 perfectly captures the epic sweep of the previous games but adds a few new features that make the game much more convenient and much more balanced.
To make a long story short, Civilization 3 is a worthy heir for the franchise and a definite must have for any strategy gamer who doesn't want us to make fun of them.
