RoWorld Cities Guide: Troop Capacity and Development

Last updated 2026-10-26Unofficial player article

Quick answer

  • A city increases your nation troop capacity.
  • The documented city increase is 25,000; this is not a claim about every upgrade level.
  • Capacity and the army currently available for attacks are different things.

Cities give the army more room

RoWorld cities increase troop capacity. The gameplay guide states a 25,000 increase for a city, and the RoWorld walkthrough describes the same population-cap effect.

RoWorld Cities Guide GameplayUse cities for army capacity without confusing a higher cap with troops already available.

This gives city development a concrete role when your nation needs room for a larger army.

A higher cap is not the same as an army already waiting to attack. Keep the troops you currently hold separate from the capacity they can grow toward when planning the next commitment.

Decide whether capacity is the immediate problem

If your main difficulty is funding construction, a city and an income building solve different problems. Factories and ports support gold income, while the city addresses capacity. Choose according to the next action your nation needs rather than treating one building as the answer to every slowdown.

On a threatened border, defensive preparation may take priority over another capacity purchase. More room for troops does not remove an incoming attack.

Develop an existing location deliberately

The guide describes clicking an existing city again to upgrade it. Decide whether you want to improve that location or place another city as your territory grows. Keep important infrastructure in your wider defense plan, particularly once missiles enter the match.

Use build cities for a new construction decision, or city upgrades for improving an existing city. Those choices belong in the development of a nation you can continue to hold.
