I think adding new religions, and allowing inquisitions would be a good addition to the game. Inquisitions would of course attack non-state faiths in a city, which could get rid of the religion in that city or just cause a diaspora. I dont know if the inquisition would hurt or help happiness.
New religions? Zoroastrianism, Vodun, Shamanism, and "Nahuaism" (some other name for the Aztec faith)?
