Can an inquisitor actually kill the religion completely? as in : its no longer on the world religions list?
If so : would that free up another civ to start a new religion?
I think the holy city asserts a considerable amount of base pressure upon itself , so , if the city was completely converted to another religion , its original faith would slowly grow back. I usually play on marathon where : a holy city exerts 10 pressure upon itself ,a grand temple increases the internal pressure to 20 , and , a regular religion adopted city exerts 2 pressure on to cities , there are beliefs that can give pressure bonuses. The pressure radius is 10 plots. Trade routes exert 2 pressure from either city. trade routes to holy cities exert more. So , you could arrange the neighboring cities and trade routes in such a fashion to outpace the internal pressure where the religion is stifled from returning.
A question this brings up : you can make ANY of your cities the holy city by moving your prophet there and then having it found the religion. The AI will ALWAYS found at the capital ,but , nevertheless , the question : can a holy city that is NOT a cap or conquered CS be razed?
I never tried this : could you found in a conquered CS or capital? If so : what happens if its liberated? Does the restored civ now own the religion? , and , WTF would a CS do with its own religion? would it crash the game , or what? ,and........ if you can't raze a non cap holy city , is it then a good strategy to found away from your cap to have two non-razable cities?
