No, I'm not talking about Inquisitors. In the base game, you found a religion and it's there forever. But as we know that's not the case in the real world. Inquisitors have been done, as has gradual fading (I think), but that's too small-scale for what I want to do. I want to make religions vanish completely. I envisage it thus: Religions are founded as normal then, after a set number of turns they "expire". The religion disappears from every city and its buildings become obsolete. This would allow more religions to be added without making it so pretty much every civ gets a religion all to themselves. It's also a key part of a mod idea I've been toying with, which I may or may not actually make. My question is, how can I do this?
