Does anyone else think that adding Holy Wars would be an interesting addition? Basically how I see it might work would be like this:
Any civ that controls the holy city for a certain religion could (for a certain cost) declare a holy war on another civ. This other civ would have to be a different state religion than your own. Any city (in any civilization) with your religion would get some hapiness bonus if that city's civ is at war with the "heathen" civ
and one unhapiness point if they are NOT at war with the "heathens". A holy war would last a certain number of turns.
This would add a little more incentive to spread your religion around in order to get a bit of support for any wars you might want to fight. The downside from not participating in the holy war isn't major enough to force everyone into wars at your every whim and the benefit from participating in the war means you're able to fight for longer because your war weariness is being offset. And it adds a little bit more character to the religious aspect of the game.
This framework would be generic across all the religions so we could hold Crusades, Jihads, etc.
