My aim was to build the city with the maximum possible number of houses of the best quality possible and also mix some patricians with the plebs. Since it's possible to import 25oil and wine (15 oil initially, for a long long time. Waited some 10 years more than I needed to win the map with all GI or above, just to get the increased route to build some 40 or something more houses), the maximum number of houses would be ~104.
Ended up with 79 GIs and 25Large/Grand Villas. It was fun trying to control the evolution of the GI by holding back the desirability.
It was also a good challenge for me trying to use the least getting granaries/warehouses as I could without making the city unstable.
