Chieftain
I'm play on Emperor/Epic/Standard, have 2 cities, and I'm currently saving 1 social policy for when I get to the Industrial Era because I already have 3 completed Branches. And I'm in the lead in science, religion, and money. The latter 2 by a landslide. And, because of that, I'm passively getting ahead diplomatically because I'm guaranteed to win any City-State quest that entails generating the most of a yield in a certain amount of turns. The stacking Science/Culture bonus in Arabia's UA is ridiculous. And hilariously fun. Probably because I love Social Policies.
