Great People are wonderful, but if you're like me, there comes a point in almost every game when your cities start producing Great Prophets. The first one is very nice, because he lets you build a shrine and rake in money for your state religion. If you had multiple religions, the others might be helpful too. But eventually you run out of shrines that you can build and you end up with more Great Prophets who can only be used to create specialists who will create even more Great Prophets. Sure they can discover technologies, but unlike Great Scientists and others, the eligible techs run out fairly soon and you're left hoping that another type of Great Person will show up so that you can at least start a Golden Age. I think that this is a problem.
Look at the other great people; they all have a couple of inexhaustable abilities. There's the tech gains, the merchant caravans, the culture bombs, and the military experience points. We need something more for the Prophet.
In the general forum, a thread called Real Religions put forth a lot of ideas. Whether most were doable or not was never answered and the person who posted it hasn't been around for a while. But among the suggestions was a Pilgrimage ability for the Great Prophet.
What is the Pilgrimage ability? If a Great Prophet is in a Holy City, you can perform the Pilgrimage to generate instant commerce and culture (less than the Great Artist culture bomb for balance's sake). This could be done an infinite amount of times. Suddenly, those Great Prophets would have a purpose in life, and wouldn't we all appreciate that?
I assume that this would need to be in SDK, and I have no abilities there at all. I'm just trying to learn how to change things in XML right now. If somebody could program this though, I'm sure that I and many others here would be most grateful. Thanks.
