A level 8 Imperius capital.

Cities are the foundation of any empire in Polytopia. They are buildings on the map that produce stars and let you train units. Cities are first acquired from capturing villages, and can be conquered from opposing tribes once settled.A player is eliminated when they have lost all their cities.

Cities can be upgraded by increasing population, done through various methods (i.e. harvesting fruit, building farms). Each time a city levels up, the city's star production goes up by 1 star. During the first three upgrades, the city can be given unique features such as workshop, city walls and border expansion, or the player can choose bonuses such as population growth or an explorer to scout the surrounding tiles.

If an enemy unit or Nature Bunny moves onto a friendly city, star production from that city will stop entirely and you will gain 0 stars from it the next turn.

Units in their tribe's city get a 150% defense buff, which increases to 400% if the city has city walls.

All cities of the same level, same tribe and same upgrades will look the same. The capital will have the tribe prism on top of the Workshop, if present.

Capital Edit

The Capital is the player's starting city. Capitals produce by default 1 more star per turn than other owned cities. Cities can be connected to capitals through the use of roads and ports. Each capital contains a prism specific to each tribe that lingers even if the city is captured. (e.g If the Kickoo takes the Oumaji Capital, the Oumaji prism will still stay there.) The name of the captital is also underlined. Capturing another tribe's capital will disable any trade routes they have in place until the city is taken back.

Territory Edit

Territory is the area surrounding a city that belongs to a tribe. Buildings may only be constructed in this area (with the exception of Roads, which can be built in unclaimed territories as well). Units, however, can only be trained in the city itself. Territory is marked by a dashed line with the color of the owner's tribe. Territory borders can be expanded once a city reaches level 4, when the player is given the option to expand borders or increase population.

The territory around a city is a 3x3 square with the city in the core tile, giving the player a total of 8 workable tiles to start with. If borders are expanded once level 4 is reaches, the territory becomes a 5x5 square, increasing owned workable tiles to 24.

If two cities are close to each other, territory will be claimed by the first to emerge. For example, if two villages are located close to each other and one is captured, it will occupy the usual 3x3 square once founded and 5x5 once upgraded, even if it takes over the potential tiles that would be within the other city's sphere of influence had it not claimed it. Once the second village is converted into a city, it will claim all tiles within that 3x3 square that have not yet been taken by another city, with the same happening during border expansion. Once the territory is defined, it cannot be exchanged between the cities. This remains true whether the cities belong to the same tribe or to different ones.
