This is inspired by GovernorSimulus' maximum population quest. but instead of fitting as many people in a map, I'll focus on getting 12k population in Old Kingdom period.
My personal rules in this quest will be:
* Very hard difficulty
* 12,000 population
* 100 prosperity rating
* All houses are residences or better
* All roads are connected, optional for entertainment venue
* All schools, libraries, mortuaries and senet houses are well supplied.
* Personal funds only used for kingdom rating
* Smooth population census - no aging problem
* Final city should runs with minimal intervention
There are 40 stately manors and 89 common residences living peacefully inside 5 riverside neighbourhoods, run by 1910 workers. 5 schools, 2 libraries, 2 mortuaries and 2 senet houses are adequately supplied. All roads are connected since the narrow rivers do not hinder ferry capacity much.
Problem #1: Land is at a premium here
I used housing blocks that are tailored to the narrow terrain. Then, proceed to fill the leftover corners with industries and slot entertainment venue / monuments into whatever pocket space I managed to find.
To fully utilize those awkward spaces, the north manor block uses 64 squares loop while the southwest one uses 70. As a result, some services only make a round trip 1/4 of their cycle, reaching the furthest manors seconds before they start devolving.
Problem #2: Distribution problem
Once the dock location had been decided, I drew a shortest path from it to the last island as the main distribution line. Then built several redundant storage yards near the 4th island to serve the last 3 islands. These storage yards and the two grain granaries are carefully placed within 40 squares from all bazaars to further shorten the distribution distance. Also, every storage yards receive only one of beer/linen/papyrus to maximize their efficiency.
More redundant storage yards at the dock area to receive the amount of beer/papyrus set in the overseer of commerce, solely to avoid dock worker pushing to the furthest storage yard because the nearest only has space for 3 units.
In addition, I decided to import papyrus but not reed, so the reed gatherers wouldn't dutifully embark his epic journey to the east.
