One civic I've been thinking about recently is Syncretism. I think it works well as far as gameplay goes, but I struggle with what it's supposed to represent. The obvious thoughts would be Hindu-Buddhist kingdoms in SE Asia and the interplay of indigenous religions with Catholicism and Islam, but neither of those fit mechanically since Hindus and Buddhists tolerate each other and there's no representation of pagan religions once an organized religion is spread to a city. Because of that, it feels like the civic exists for the Kushans and Korea and not really anybody else. I'm not sure whether it would be better to go back to the Tolerance civic that we had on the smaller map or try to find more situations where syncretism makes logical and gameplay sense--the only other example I can think of is a China with a lot of Buddhist cities.
