Through the Ages: A Story of Civilization

You may only play cards when you take the appropriate action on your turn (for example taking/playing Civil, Technology or Military cards); you cannot play cards outside your turn. See rulebook pages 4–5.

During Production you must pay food for your population; if you cannot, you must immediately reduce population (disband workers/units) until you can pay, which can cause loss of workers and other penalties. See pages 6 and 9.

Event cards are drawn and resolved as part of the round sequence (after the first round) and are handled according to the event text; some events are immediate and others are future events with a specific resolution procedure. See pages 8 and 12.

Aggression (brown) cards trigger combat that is resolved by comparing military strength from your units (modified by Tactics/Armies and card effects); military cards and tactics change how strength is calculated and are applied during combat resolution. See pages 13 and 16.

You can change government peacefully by paying the indicated cost when taking the change-government action, or you may trigger a Revolution if you cannot/will not pay; both peaceful change and Revolution procedures are described in the rules. See page 8.

Happiness affects the risk of uprisings and certain population penalties, while corruption (advanced rule) reduces effective resource production until mitigated; the rulebook explains how happiness, uprisings and corruption interact with examples. See page 15.
