Is there any way I can make it so that only certain civs can have a particular religion? I think it would be good to limit them to the civs where the religion was prominent. One possibility I can think of (though I don't know if it would work) is to prevent the civ from researching the prerequisite tech. I don't know if that would stop the spread of the religion into that civilization's cities. I've had a look through the tutorials, but couldn't see anything about this. Can anyone help?
