0.2.0
Increased the urban maintanance and added maintanance for wonders as well.
Standard urband maintanance is -1/-2/-3 food, production and happiness
In the industrial age there are technologies which reduce the food and happiness maintance:
Electricity Mastery:
Urbanization:
Wonders have a gold maintanance cost of -2/-4/-6 now
Obsolete Buildings provide +3/+4 yields instead of +2/+3.
I my playthrough there was also less district spamming by the ai using this mod.
I recommend combining this mod with Aging Warehouses (https://forums.civfanatics.com/resources/aging-warehouses.31931/), so that it is easier to minimize the maintanance cost
