RoWorld Build Cities for Troop Capacity
Quick answer
- Construct a city when more troop capacity serves your next campaign goal.
- Choose new construction deliberately rather than confusing it with an existing-city upgrade.
- Keep the developing location away from an avoidable immediate capture.
Build for the army you want to support
A RoWorld city adds troop capacity. Before constructing one, decide what the additional room is for: a larger sustained army, preparation for a stronger opponent or continued development after your opening.
That is a clearer goal than placing a city simply because you have reached more land.
If the immediate problem is gold income, compare a factory or port instead. Capacity and funding are different needs, and buying one does not automatically address the other.
Choose the new city location
Use the city construction action for the place you intend to develop. Favor a position that fits the nation you expect to hold, rather than an exposed patch you may abandon during the next fight. This is a placement priority, not a fixed distance rule.
Check the actual construction offer before spending. Keep enough flexibility for the other job the nation currently faces, whether that is defending a border or maintaining an income plan. Avoid turning one city into an excuse to empty the rest of your budget.
Keep construction separate from upgrading
Placing a new city and upgrading an existing one are different decisions. The documented upgrade interaction is to click the existing city again. Make sure the selected action matches the location you meant to improve.
After construction, keep current troops and capacity separate when choosing an attack. The city guide explains the role, while city upgrades handles development of an established location.
