I know the company would never do this but I think it would be cool if there was a mod where having a religion allowed you to create a UU. Christian - Monastic Knights. / Buddhism – Zen warrior monks / Islam – assassin? (there are many choices) / Hinduism – Aryan warriors. Judaism – Sling men. With a little research a unit could be found for every faith and would add an interesting element to choosing and switching religion.

I can't wait to convert my people to Judaism so I can build Sling men.

I don't know, I wouldn't advocate anything more than the missionaries, no military units because that is what your army is for. If there is a way to modify the missionaries that may work. Hindu missionaries could be slow and hence never travel far outside of India. Bughist missionaries could be quick and travel all over Asia. Again, I don't have any bright ideas.

Since one of the screen shots showed more religions than one in a city, how "Unique" would it be if everyone can build one?

you can only build 'em if you own the religions "capital" city.

I was thinking you could only build the UU if you made a religion your state religion
