The rules that determine the production from the city centre tile have changed with the 1.21f patch. After checking various cities in a few different games, I came up with the following rules that seem to work. Please let me know if you find any cities that do not follow these rules.
Now let's take the city in the above example and grow it under Monarchy. As a Town of pop 1-6, we had 2/2/2 which became 2/2/4 when we increased Gold to the minimum of 4. When it becomes a City at pop 7, we have 2/3/3 which becomes 2/3/4 when we increase Gold to the minimum of 4. When it becomes a Metropolis at pop 13, we have 2/4/4 (plus 1 Shield if Industrious and 1 Gold if Commercial), Shields and Gold are at or above the minimum, so no further adjustment is needed.
- Start with the production of the tile on which the city is built (including resources and bonuses).
- In the case of Forest, use the production of the underlying terrain (Grassland, Plains or Tundra).
- Change Food production to 2 (Food production is always 2 for city centre tiles).
- Add 1 gold (city centre tile contains a Road).
- Add 1 Shield and 1 Gold for pop 7+ City.
- Add another 1 Shield and 1 Gold for pop 13+ Metropolis.
- For pop 13+ Metropolis add another Shield if Industrious and another Gold if Commercial.
- If the resulting Shields are less than 1, increase to 1.
- If the resulting Gold is less than 4, increase to 4.
- Add 1 Gold if under Republic or Democracy.
- Add 1 Gold if Colossus is in the city.
- If under Despotism or Anarchy, the 3rd Food/Shield/Gold from each tile is lost.
