The aim of the game had become :
70,000 inhabitants in a forever running Alexandria with its five monuments.
Target reached ! Bypassed even.
The city submitted reaches currently 68,600. I simply played it as described below, for fun, and reached 75,000. But I prefer you to watch it the way it looks now.
Most people live in 378 manors. Unemployment is slowly stabilizing in the 20-24% range. Anyway, people in this city could stand for year up to 30% still adoring Pharaoh.
The city is very stable except for the entertainers that have to be checked out : they can work one year without trouble then mess up miserably for the following year. It worked nearly perfectly until I connected the housing blocks South to the network North.
The 31-32 spacious manors block works perfectly. One school accident only after 55 years of game, no accident with anybody else, except one freak school fire say every three years.
Some 3-4 taxmen were withdrawn when I made bad calculation of the space left and had to find a tile somewhere. All blocks have two bazaars to ensure full stability. All bazaars except two in the same block SW have 20,000 of everything, for the two remaining one has the fish, the other has the grain : the food SY were simply too far away from the block.
So, to go beyond the current figures : you can withdraw all taxmen except one, just to ensure you make money. This will allow you to reach 70,000 people.
You can withdraw 16 bazaars and set 1472 more people. There is enough room to set another housing block SE of 30 fancy residences. There is still a margin in consumption of linen, and papyrus that correspond to another school (two would cause overconsumption of papyrus, unless a redundant trade blessing from Ra). As said, you already reach an easy 74,000 people.
There is also much room left for more houses. The data limit will not be reached ; It has not yet been and many items can be removed including all fishing wharfs (enough fish can be imported), luxury factories (idem) and many small-medium statues.
Therefore a stable city of 75,000 is reached without trouble, 80,000 maybe is possible.
