In the Community Balance Patch, social policies have been changed dramatically with the reforming of every policy tree. Also, the 9 social branches are divided into 3 specific eras: Tradition, Progress (Liberty), and Authority (Honor) unlock in the Ancient Era; Piety, Statecraft (Patronage), and Aesthetics unlock in the Medieval Era; and Industry (Commerce), Imperialism (Exploration), and Rationalism unlock in the Industrial Era. Order, Autocracy, and Freedom can now only be adopted as an Ideology once you complete three social policy branches or reach the Atomic Era. You also earn cumulative benefits for adopting multiple policies from the same tree. Finally, some World Wonders are now linked to different trees and some have been unlinked. (For example, the Pyramids were linked to the Liberty tree, but now the Parthenon has taken its place.) Wonders linked to policy trees can only be built if the relevant tree has been completed and you have researched the necessary technology.

The next Tier of policies can be unlocked by getting 6 other Policies or advancing 2 Eras. Ideologies would need 18 Policies and Industrial or Atomic Era.

The previous system was needing 3 Finishers for Ideologies.
