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.

We've tried to revitalize Culture but we're still using really unproven New Methods instead of looking at the Core CIV IV/BtS ways and making them stronger. Fixed Borders, Realistic Culture Spread are all really relatively new methods game wise. Now that they have been used and reworked I believe we are finding out that their premise was flawed in terms of Core game mechanics. Instead of enhancing Culture and Espionage they actually weakened them. I'm actually in favor of them being removed (Please!, don't throw stones now, I know no one likes to have less choices, I'm that way too, but if it's destroying a core game feature/design then something has to give).

I personally would love to see tile flipping from Culture come back to it's roots, Culture Units reinstated (entertainers, artists, and the Culture Bomb). Only this time working on the AI to be Better at utilizing them (they did use them in the past but not as often as the player.) And those that abused them came and started declaring to the forum that they were eXpliots and Cheats, so the Modders killed them off. Those units were not the problem. The players that overused them and then cried foul was the real problem. Helping the AI to be more adept at their usage was the real solution but it was discarded.
If the AI used a Great artist (Culture bomb) on it's border city to claim some of your border tiles the player would have a fit. But when you did it to the AI it was Oh So sweet! Until you realized that the AI wasn't as good as you at building and using those units. Then it became an eXploit and a cheat. That was wrong thinking. Instead of helping the AI use them better we killed them off instead to assuage our egos. And our willingness to cheat and not be held accountable for our actions. We weakened our foe by taking away some of his options/tools. Lets give him back his options and tools so that we Have to guard against him taking our tiles..
