Prepare to accept history's greatest challenge: build the world's most powerful empire over a 6,300 year time span, reaching from primitive history to the future realms of science fiction. It's your time to rule - answer the Call to Power.

Build the Greatest Empire
Command your people by military, economic, scientific and cultural decisions. Manage the growth of your cities, explore new land, and exploit the world's resources as you vie for power.

Rewrite History Your Way
Built-in scenarios allow you to relive some of the world's greatest battles. A map and scenario editor allow you to build your own historical or fictional situations.

Use Diplomacy Wisely
A completely new diplomatic model allows you to offer proposals and negotiate counter-proposals with other empires. React in friendly or hostile tones as you confront distinct opponents with more in-depth AI personalities for even more realism. Utilize all-new diplomatic options such as Borders to help define the geopolitical situation.

Decide How to Lead
New management features allow you to control your empire the way that you want. Manage the labor, production and economic situation in each of your cities, or leave the micromanagement to ministers and advisors while you concentrate on the most pressing affairs of your empire.
