Deterministic living-city simulation

Build the city. Run the economy.

Equity City

A player-first city sim where jobs, wages, contracts, and company control unfold inside a fully deterministic economy. The latest Phase 1 update shares fixed-seed stability checks, large-map runtime evidence, and a city that is becoming more readable at a glance.

Current build feel

Readable scale, visible systems, and a city you can actually operate.

Why it feels different

Simulation depth turned into visible game feel.

This is not a black box economy. The site should show why the city is interesting to run, not only that the code exists.

A living economy, not a fake meter

Companies hire, citizens work, contracts settle, and the city's balance moves because simulated actors are actually making choices inside the model.

Systems you can read while they run

Debug HUDs, Telex events, and observability tooling make the city legible. The point is not hidden math. The point is watching the machine think.

Growth that stays readable at scale

From zoning blocks to dense street walls, the city keeps its shape. You can zoom out for macro structure and still trust what you're seeing up close.

Week 7: Advanced Economics (Equity & Control)

In a capitalist city simulation, the CEO is king. But what if the CEO is just an employee of the shareholders? This week, we implemented the final piece of the economic puzzle: Equity & Con…
