Game concept
Cultural Acceptance
From the game's encyclopedia
Cultural Acceptance measures how accepting two Cultures are of each other.
Primarily, it affects how much Opinion is reduced between Characters of different Cultures. It also affects Popular Opinion, and the cost of forming a Hybrid Culture.
Cultural Acceptance can change from many actions, most notably Wars, granting and revoking Titles, and the Promote Cultural Acceptance Councillor Task.
Over time, Acceptance will return to the Cultural Acceptance Baseline if exceeded.
