if i might make a suggestion, i think that you should handle the "religiousness" the way that AoE3 did. The Ottoman faction had a mosque (as opposed to a church, like the other factions), and they had an imam instead of a cleric. even though they were different from the rest, they still did the same things that their Christian counterparts did (only differences were in name, appearance, and picture). now, i have no problem with making them different from another form of holy man, it's just that there is a line there.
sorry if im not making much sense, but im trying to prevent any anti-muslim remarks because of this mod. it's a touchy subject here in America
