So yeah could we even attempt such a system now with all the new property systems and stuff?
How would property systems play into ordinances?
No idea. That's why I was asking.
How about having Ordinances as locally constructable "buildings" and National Wonders that apply these Ordinances to every city? Only problem might be in "repealing" them (I don't think you can delete free buildings or wonders)...
Alcohol Prohibition replace lot fo buildings. I think it should Remove access to Alcohol (and others alcohol related ressource), like Mormon Shrine.
A funny ideay would be to add a Crime (Illegal Distillery), giving a Frelated Alcohol ressource. This ressource is like alcohol, but with more unhealth ^^
Similar thing for Drugs Prohibition
How about, "royal decrees" in the earlier phase of the game, and "ordinances" in later phase of the game?
Obviously, royal decrees are going to be weaker than ordinances, and also they'll be either replaced by them, or obsoleted by the tech that gives you the said ordinance.
