I originally wanted to have all the branches of Christianity (3), Judaism and Himduism (5), and Buddhism, Atheism, and Islam (8) and Polytheism (9), but that's too much, so I narrrowed it down. Hinduism has just one big country as it's follower (India) and Atheism is a communist thing, not really a 'National Religion'. The reason I didn't call Polytheism Paganism is that to me, a Pagan is something that people once worshiped, but Is considered false, such as the Norse Gods, but the Hindu's believe in more than one God, and I'm sure they don't think of themselves as Pagans. Also, some people in back-water Mexico still worship Quatzcoatl (or however you spell it) and Tlactoc in times of drought. I think I'll keep Polytheism, Polytheism.
Also, I don't think any country still largely is Buddisht, except for Nepal and Bhutan, but they aren't in CivIII. Taoism is still a large religion, but I count it under Polythiesm (although it really isn't) and actually Zoroastrianism makes more since to include than Judaism as Persia once was Jewish, but was mostly Zoroastrianic(?). I might add that in an update. Thanks guys.
