Strategy guide

Regional effects from Industrial Zones, Water Parks and Entertainment Complexes reach 3 tiles further — a 9-tile factory radius. Plan one central Industrial Zone hub to power six or seven cities instead of building factories everywhere, and spend the saved production elsewhere.

Best civs & plans

Germany's Hansa hubs and any tightly-packed empire profit most; the amenity radius also stretches one Colosseum-style investment across more cities.

Envoy plan

Mexico City is an industrial city-state, so envoys parked here always produce something: faster districts, buildings and wonders in the capital and Workshop cities at one envoy, Factory and Consulate cities at three. That makes it a safe early home for a spare envoy even before the suzerain bonus matters. Aim for three envoys as your first Industrial Zone approaches, usually late medieval, so the extended radius is active when the Factory lands. AI industrial civs will compete, so plan on holding five through the industrial era. Six envoys pays off doubly here, since the Power Plant tier boosts the very hub city whose regional reach the bonus extends.

Value by era

Nothing happens in the ancient and classical eras beyond the envoy tiers; the bonus waits for Apprenticeship and the first Industrial Zone. The medieval and renaissance eras are the planning window, when city placement decides how many settlements will fall inside a nine-tile radius. The peak is the industrial era: a Factory and then a Coal Power Plant in one hub city broadcast production across nearly the whole empire, and the extended Entertainment Complex and Water Park reach solves amenities in cities that never build their own. The value holds into the atomic era as Nuclear Power Plants replace coal, and only fades when every city has its own district anyway, which a dense empire never needs to do.

Pitfalls and how to protect it

Regional effects do not stack, so two Factories covering the same city give it one Factory's worth; the mistake is building Industrial Zones in every city out of habit and wasting the radius. Pick one or two hubs on high-adjacency spots and let the others skip the district. Remember the radius is measured from the district tile, not the city center, so nudging a hub toward the empire's middle covers more. Cities settled far apart for luxury grabs will sit outside even the extended reach; that is a settling decision, not a Mexico City failure. Losing suzerainty shrinks the radius back to six tiles at once, which can drop several cities off the grid mid-build, so guard the lead. If an AI captures Mexico City, liberation is worth a small expedition for an industrial empire.

Envoy bonuses

  • 1 envoy+1 Production toward wonders, buildings and districts in your capital and in each city with a Workshop.
  • 3 envoys+2 Production toward wonders, buildings and districts in each city with a Factory or a Consulate (+4 if the city has both).
  • 6 envoys+3 Production toward wonders, buildings and districts in each city with a Power Plant or a Chancery (+6 if the city has both).

Envoy bonuses are shared by every city-state of the same type.
