Except that with the latest buildings espionage is broken. The AI does not consider the espionage down side to buildings and end up with no espionage points something that used to just accrue through out the game. The chance of success of a spy mission is based on the total espionage points you have compared to the total your target has. With the new buildings most AI have zero espionage points. I think Fixed Borders is working but realistic Cultural Spread is not there yet. Yes both have changed the way culture works but I don't see it as having broken it completely if at all. And, as far as I can see neither has had any effect on espionage. I agree that the removal of the cultural bomb units was a mistake. A better solution in my opinion would have been to 1) get the AI to use them and 2) remove the part that reduced anarchy in the recently conquered city. Or make it manditory and have the AI do it also. Other changes like the Great Farmer and the random discovery of resources like stone have broken the trade system. The latter has been around since RoM 1.something and I have complained ever since. Just not as often or as loudly as Joseph.
