Age of Chaos is a new way to play Age of History.
Every 20 years, you will have to change the Civilization you control and switch to a new one.

You will be given four random Civilization to choose from.
Pick one and continue your journey, even if it means one day fighting the empire you once ruled.

Before starting a new game, click on Settings, and in the menu, you can enable Age of Chaos mode.

You can also change the time period when the Age of Chaos (Change of Civilization) happens.

Have fun!

The default duration of the Age of Chaos has been changed from 10 years to 20 years.

This has been fixed in the update.

Province Optimization Regions help reduce the number of calculations required when rendering all of the provinces.

Once your army is much bigger, the ultimatum should be accepted.
