Each city AT THE MOMENT, is productive but that could change once I start Raiding teh Greeks.
Just out of curiosity, how many shields are you pulling down in old Rome? Can't be too many from the looks of the map. Why did you choose to build a wonder there - especially since you can't switch to a palace build if a cascade leaves you with nothing else?
I have about 20 workers, and a minimum of 2 muskets in each city.
This might also be part of the problem - 2 muskets per city is a drain on your offensive campaign. Do you really need 2 muskets per city for defense? Are they ever going to reach Rome, Cumae, Veli or Pompeii? If not, no need to load up on the defensive units - or move them somewhere they can help the advance. A small group of quick reacting offensive units in the area might stop any ship landings. I rarely stock 2 defensive units per city. I think I read that recommendation somewhere in the forum and took it to heart.
Aside from the Courthouse topic, you are also building a Colosseum. Are you really having enough happiness problems to warrant the shield cost and upkeep? It might make sense depending on your victory goal, but this is another building I find is usually just not worth it. One thing to keep in mind is that every shield you spend on the Colosseum is a shield you don't have to build an offensive or bombarding unit.
One other quick analysis - the Colosseum cost 2gp per turn to maintain. You just disbanded (?) your obsolete units. In Monarchy, those units can be used as military police and as defense/attack units in a pinch. Two units gives the same happiness as a colosseum, and the colosseum, no matter how lucky the RNG, cannot destroy a tank! That spearman just might get lucky . . . Besides, you already spent the shields to build the units. Why pay double? If I am in Monarchy, I almost never disband units. Use them up - who cares about war weariness?

Or use them for MP duty and send your good units out to fight.
In closing, let me say that I am glad you stuck with the game rather than dropping it. I will be interested to see how it develops. I am a monarch player that is looking to go for Emperor soon. So if I can be of some assitance to you, then maybe I have repayed some of the kindness the other players on this forum have shown me! Good luck!
