This one was a bit of work, especially toward the end as I "perfected" the city and replayed each of the last few years several times. Nonetheless I feel this Carthago is quite nice. It holds well over the population requirement because I "choose to govern for 5 more years." Technically there is room for 5 more people, but my penultimate immigrant didn't arrive in time for victory in February 142 BC.
The city consists of a eastern and western half which are disconnected road networks with the eastern half, because of its greater fruit supply, hosting the palaces. I had some serious labor shortages when I was reaching the population goal, so I had a crash program to get as many Grand Insulas in town as possible and managed to fit about 10-12 I did not originally plan to have. Food was vary abundant though, so that was no big problem really. Some of the Grand Insulas, especially in the western half of the city, had some colloseum access problems with the lion tamer coming around the block just too infrequently, so some would devolve, then rapidly re-evolve, to Large Insulas. Needless to say with 8 Lux Palaces this had absolutely no effect on my prosperity.
Like in Miletus, I had some pottery/furniture distribution problems. Each half of the city has its own pottery and furniture workshops, a warehouse for each and for clay/timber imports. Unfortunately, and I I don't know if this was simply confusion fro my tendency toward micromanaging turning each warehouse to accepting and not accepting clay and timber to "balance out" the two sides of the city, Thamugabi vary often wouldn't sell their full quota of 25 clay and 25 timber to me and my precious pottery and furniture supply would dwindle some years. I also had a bit of a precarious situation with oil as I had to turn that industry off to save some workers at the height of the worker shortage.
I controlled access to wine by making all my plebs "girl god" monotheists, those in the east worshiping only Venus and those in the west only Ceres. All the "boy gods" were worshiped only by the patricians, with a large temple to each Mars, Neptune and Mercury along the disconnected wheat-supplying road behind the palaces.
The save is from Dec 144 BC, 14 months before my extra governorial tenure is up, to give you a full year to watch my city at its climax. I decided not to max out culture because of the severe labor shortage toward the end of the city, a combination of the great number of services demanded by Grand Insulas and an aging population.
I did not rigorously apply my usual rules to this city. However I did not accept bailout money, did not give the city any of my personal funds and there were no internal gatehouses.
