I want to take a founder belief which will provide additional happiness. I'm unsure about the benefits of Ceremonial Burial vs. Peace Loving:
+1 Happiness for each city following this religion
+1 Happiness for every 5 followers of this religion in non-enemy foreign cities
What are the precise benefits here, and under what conditions should I choose what? And is Peace Loving also applies for city-states, so I can rely on those as well?
