There are 6 different policy types, and 4 policy slots. All types must be applied to an empty slot of the same type in the government, but a Wildcard slot can house any type of policy.
Military: These policies are best for players who want a strong military on land and sea.
Economic: These policies can be useful in increasing all sorts of yields, whether through increasing district adjacency bonuses or reducing costs.
Diplomatic: These policies are best for players with a strong interest in building relationships, and can help strengthen the bonds with city-states or improve espionage operations.
Wildcard: These policies have varied and powerful effects, but can only be used with a Wildcard policy slot.
Government: These policies provide powerful legacy bonuses for different Government types. They are unlocked when you build a Government Plaza district and one of the buildings corresponding to the tier of a Government. For example, if you adopt the Classical Republic Government, and then construct a Warlord's Throne, Ancestral Hall, or Audience Chamber, you'll unlock the Republican Legacy Policy.
Dark Age: If you enter a Dark Age, you can gain access to special Policies that apply only while you are in a Dark Age. The selection of Dark Age Policies will change as the Eras advance. These policies can provide you with a special advantage that might help you, but have a cost that may restrict you in other ways.
