Yes, that was my initial thought(and what I did). The full explanation is this:
I am working on a complete religion system. So far, the things that work fully are these:
-there are 4 religions, Catholic Christian, Orthodox christian, Islam, Tengrism
-religion is assigned according to culture
-there are custom map locations of monasteries, where the player can buy wine, visit the scriptorium, pray, hold a memorial service for dead part members etc. Also, an altar for tengrism, where players can pray
-there are town chapels and mosques, assigned to the initial faction ownership of each town. The Sarranid towns always have mosques(because they are built before the start of the player's adventures) and continue to have them even conquered. Only players with same religion can visit each according temple.
- Monasteries and altar are "raidable" and altar is destructible
And other, minor changes. Now, I am working on faction relations according to religion and Holy Wars. Basically, the fanatics of the game will be Sarranids and Swadians. First with Jihad, second with Crusade. So, I'm looking for a way to initiate war when certain conditions are ticked, not just worsen relations.
