Player City

Player-owned cities are cities owned, managed, named, and developed by players as opposed to NPCs such as Demon cities.

Population
A city's population is calculated by the buildings that have been created in that city. The city's daily taxes are also calculated from the city's population. City population may be calculated by first adding up the total number of constructed buildings, then add the level of each building. For example, a newly-founded city begins with a single building, level 1 city hall. The total starting population of the city is 2. Next you build a level 1 farm, adding the farm building and its first level, so your city population jumps from 2 to 4. Add a city wall and your city population leaps from 4 to 6. However, when you upgrade an existing building, you're only raising its level by one. So when you update your farm from level 1 to level 2, your population only jumps by 1, so your city population raises from 6 to 7.

Daily taxes are based on the city's prosperity, which is essentially equivalent to the city's population. For example, the city of Gracely has 119 population and Gracely's prosperity is 11%. The city of GanGaree has a population of 685 and a prosperity of 68%, etc. The city's daily taxes are roughly 10 gold per person in your city's population. So Gracely's daily tax total is roughly 1190 gold, while GanGaree rakes in more like 6850 gold a day.
