I usually aim to invest on City States from the food buff, but, can someone explain me this one policy? "Cultural Diplomacy +100% more resources and +50% more Happiness from City-States " 100% more resources is on the luxury resource that the city state has? Or the food, or cultural buff as well? 50% more happiness from city states. what happiness? City-states don't give happiness, kinda blind on this one. cheers.
