Will there be any unit such as an Inquisitor to banish religions off a city?
Nice idea, but I think it should cause discontent as well, perhaps dependent on how long the respective religions have been present in the city. Indeed, enough persecution in real life would certainly prejudice other nations who followed the persecuted religion against you.
Tough to totally eliminate a religion from a culture. Even the Inquisition had very uneven results. Anything the enhances the cutlural/economic side of the game I'm in favor of. But this would be really difficult to exectue (please pardon the terrible pun).
The Inquisitor (or SS team, or Jihadist or whatever) cracks down on local relgion. What happens? Drop in population? Drop in or increase in city hapiness? International considerations? I suppose if a city stopped following an foreign religion, then the other cutlure would automatically suffer financially, but would that be worth the risk/cost?
Probably more trouble than its worth to develop.
I don't expect to see it in the game for the same reason Hitler isn't in, anything that allows genocide and persecution in the game is going to be hard to get in especially when it comes to religion (which is why they made all the religions in Civ IV exactly the same)
