Paladin,
"ECS no-agents" is actually very popular,
would it be possible to include a no-agents compatible version of your campaign in the download?
"ECS no-agents" allows only emissaries and princesses,
completely removes taverns(assassin), brothels(spy), monestary(Inq.) and Reliquery(Grand Inq.), and corresponding Muslim buildings,
But enhances the happiness factor of churchs/mosques to compensate,
it is actually very playable,
the occaisional wish for an assasin is negated by keeping a carefull eye on the pope, and only offending him when he is 70+
- 'cause he will die soon anyway http://www.totalwar.org/ubb/smile.gif
OR by attacking a cath faction that is small, then when you get the warning take on your real threat!
Pope only tracks one warning at a time.
