So you're basically shooting yourself in the foot (founding a religion has no negative game effect outside your control) to create a more realistic/fun game experience? I do the same, but we shouldn't have to. I can see how playing with more than the standard seven would decrease the impact of the problem (since no of religions doesn't scale with map size etc), but wasn't the religion system supposed to be balanced on standard? I can't imagine giving a prophet would help all THAT much. Most of the cities by that era would have a religion, I would think, which certainly was not the case in pre-Islamic Arabia et al.
