Have you thought about WHY there is this limitation to only building temples for your own religion and that it might serve a gameplay purpose?
Honestly? I hadn't. Can you tell me what the gameplay purpose is?
This wasn't intended to gain any sort of unfair advantage or circumvent any mechanics. We just wanted to create a religious district with a number of temples in it. Something that we could do RPs about and add flavour to the city and to our realm.
