One shared world, running right now

Own the road.
Own the grid.

EconoCity is a city where the other players are the economy. Buy land, pave the road that makes it worth something, run power and water out to it, then set your prices. One map, one grid, one stream of residents looking for somewhere better.

How it plays

Your first hour, roughly

Five things, in this order. Nothing is locked behind a tutorial, and all of it can be undone by somebody putting a road somewhere clever.

01

Buy some land

Drag out a lot and the city quotes you a price off what the neighbourhood is worth. Frontier land is almost free. Land beside a busy district costs years of rent.

02

Pave the frontage

Nothing can be built until it touches a road network, and no world ships with any. Lay a spine through land you already hold and your own acres become buildable.

03

Put something up

Pick from the catalogue, drop a footprint, pay, wait for the build. Then grow it block by block — outward for ground, upward for storeys, as far as your land allows.

04

Wire it up

A house with no power and no water never gets a resident. Trench a line out from a plant, pay the landowners you cross, and set what you charge per unit and per tile crossed.

05

Price it and watch

Rent, sale price, and the most you'll pay for supply. Residents arrive where the deal is best. Come back later and the district has an opinion about your numbers.

Who you can be

Nobody picks a class. You just end up with a habit.

All three make money, and all three need the other two. Most players drift into one and hire the map for the rest.

Landlord

Buy, build, set rent, and fight over a finite stream of people arriving. Push the ask too far and they start packing — rent is only ever collected on what a tenant can actually bear.

Utility operator

Generation and cable are two businesses. Sell units, charge a fee on anything crossing your tiles, and win districts on delivered price until the wires you own are full.

Land developer

Get there before anyone else. Pave the arterial that opens a whole quarter, then sell frontage, rent easements under it, and let somebody else do the building.

The economy closes

Nothing appears from nowhere

Rent from residents is the only thing that creates money in the world. Upkeep, maintenance and land tax take it back out. Every coin that moves is written down, and the whole world's books balance to zero.

Rent collected+ 18,402.55
Upkeep & maintenance− 9,118.40
Land tax− 4,860.00

Land tax is assessed on the ground alone, so sitting on prime land empty is expensive and building on it isn't punished.

The year's books

Hover your balance and you get the year so far against the same point last year: what you earned, what the estate costs to keep, what tax took, and what you put into building.

Jul 2026

Buildings grow block by block

A footprint is a set of tiles now, not a rectangle, so buildings can have holes, wrap corners and straddle two lots you own. Capacity, jobs and upkeep are counted per block.

Jun 2026

Say no to a bad price

Every building sets the most it will pay for supply. Above that it buys nothing and goes short — so the only operator reaching a district can't name any number they like.

May 2026

Land tax on ground alone

Improvements aren't taxed, so building on prime land isn't punished and sitting on it empty is expensive. Revalued once a game year.

The Discord is where the deals happen

Easements get negotiated, districts get planned, and somebody is always posting a grid they've just cornered. Come in and ask for a road.

We are guests in the #gamers-lounge channel of the PrimeGrid Discord for now. EconoCity gets a server of its own once there are enough of us to fill one.

Join the Discord Start a city first

There's a corner of the map with nothing on it yet.

Pick a spot, pave the first road, and see who builds next to you.
