Our game

Build a city.
Then keep the job.

Sovereign: Crown Rule is a city builder where the voters can remove you. Lay the streets, raise a town from thatch to towers, and govern it through elections, rivals, disasters and the people who want your chair.

A town in the Modern age, with the build menu below A tornado crossing the town

Where you build is half of it.

The other half is everyone who lives there. Twenty-one seats, five voting blocs, a rival on every grievance, and a right hand who has the garrison.

Placement matters

Works upwind poison the houses, a school three streets away is a school nobody attends. Seven overlays show what you actually built.

You can lose office

Elections are uncertain and towns tire of a government. Lose the chamber and the game is over, with a named rival who took it on a named cause.

Four ages and beyond

Settlement, Colonial, Industrial and Modern, then automation: rail, highways, data centres and the question of what work is for.

Seen coming

Tornadoes, cyclones, eruptions and meteors arrive with weeks of warning, and strike on the music's climax.

Six institutions

The chamber, the courts, the church, the unions, the colleges and the traditional owners, each with its own grievance and its own power.

Retire with honour

Survive long enough, keep the town behind you, and step down on your own terms with a legacy worth reading.

Pay once. That is the whole deal.
