Civilization IV is a historical-simulation game where players develop factions throughout the known history of mankind. Players build cities which produce the structures and units of the game and are the source of income and technological growth. As time progresses factions will discover new technologies which allow them to improve their cities and build more things.

Each faction is led by at least one historical figure famous in history. Diplomatic relations between different factions are represented by interactions between these historical avatars. Everything is cool until someone gets stupid and destroys my work boats.
