城市

在《英白拉多：罗马》中，城市（City）是土地的最小单位。几个城市组成省份，而几个省份组成区域。

城市机制

Fixed:

• Each city has a given 地形类型.
• Each city produces one item of a single type of trade good for its province.
• Coastal cities can have a port.
• Each nation has a fixed national capital.

变量：

• The most populous city in a province at a given time is the provincial capital.
• Each city has its own Civilization Value.
• Each city has a number of pops living in it.
• Each city can have a number of Buildings.
• Each city generates Unrest, affecting province loyalty.

Derivatives:

• Each city has its own 补给上限.
• Each port city has a chance to spawn pirates in an adjacent sea zone.

Actions
These actions can be performed from the city menu:

• Pop promotion, 文化同化, conversion, and movement.
• Cohort recruitment (some units are restricted by the availability of strategic trade goods in the city's province).
• Colonization.

首都城市

The most populous city in a province is its capital city (indicated by a marble column icon on the map) and reaps the benefits of trade good surpluses in the province. Occupying a province's capital city is necessary to demand the entire province in a peace deal.

Each nation also has a fixed national capital (indicated by a marble column with a golden wreath underneath it on the map), which is always the capital city of its province, regardless of population. All pops in the national capital have a +25% output modifier (stacking with the capital province and region modifiers), and the city also has +0.15% population growth (stacking with the capital province modifier).

港口城市与海盗

Port cities (indicated by a lighthouse icon on the map) are the only cities were triremes can dock and be recruited. Locations of port cities are fixed.

Each port city has a monthly chance to spawn pirates in an adjacent sea zone, based on the number of trade routes (both incoming and outgoing) in the city's province. Each trade route beyond the first increases the chance by +0.1%, while each trireme docked in the city decreases it by -0.1%.

If pirates spawn, they will be a universally hostile fleet, which will blockade all port cities adjacent to their sea zone, lowering commerce income in their provinces.

Some pirate fleets already exist at the start of the game.

	Desert	Local Population Growth: -0.25% Attrition: +1 Movement Cost: +10%	Arid, sandy plains stretch as far as the eye can see in every direction.

	Plains	None	A sparsely forested place, consisting of sweeping tracts of flat land.

补给上限

Base Supply Limit is 5 + 0.5 per pop in the city. It is then multipled by Supply Limit Efficiency, the base value of which is 100%, and which can be further modified by the following:

类型	修正	值
City feature	地形类型: Mountains / Marsh / Jungle	-50%
	Civilization Value	+2% per point
	Being the city's owner	+25%
Trade goods	Vegetables in the province	+10%
	Surplus of Vegetables in the province (only affects the province's capital city)	+2.5% per surplus
