Introduction: The City Can Defend Itself Now

The last few weeks made Equity City feel alive. This week was about proving that feeling holds up under pressure.

This Phase 1 update is less about a headline and more about a progress snapshot grounded in evidence. The project can now point to deterministic gameplay loops, repeatable outcomes, and large-map runtime data that make the current baseline easier to understand.

What This Update Clarifies

The March 12 commits closed the loop on the original vertical slice:

  • Start a seeded city.
  • Inspect companies, buildings, and NPC state.
  • Found or acquire a company.
  • Trigger labour actions.
  • Advance the simulation while preserving deterministic replay behavior.

That is a much stronger claim than "the systems exist." It means the team now has a clearer baseline that is becoming more playable, more testable, and more stable to build on.

Stability You Can Actually Cite

One of the most important pieces of evidence landed in the fixed-seed stability gate.

The test runs the same scripted session three consecutive times on seed 42. Each run resets the city, creates a player company, sends a job offer, acquires an NPC-owned company, advances 50 ticks, and then checks that the ending state is identical.

The recorded result stayed locked across all three runs:

  • Tick = 3180
  • StateHash = 7040308464202088643
  • PlayerCompanies = 2
  • PriceIndex = 1.0000
  • WageIndex = 1.0000

For a deterministic city sim, this is the kind of proof that turns architecture into something people can follow and verify.

Large-Map Performance Got Hard Evidence

The other big story from the March 12 update is scale.

Recorded release-mode evidence now shows the project operating inside its stated large and xlarge budgets:

  • Bootstrap: 1601.7ms
  • First 20 ticks: 23.18ms/tick average
  • Sustained 50-tick run: 25.23ms/tick average
  • Max recorded tick in that run: 40.13ms

That does not just help engineers sleep at night. It changes the public story too. Equity City is no longer only interesting when viewed close up. The city now has evidence that it can stay readable and responsive as districts fill in.

What the New Screenshot Proves

The latest March 12 screenshot is a good summary of where the project stands.

You can see dense block growth, a readable street grid, an active inspector, a live minimap, and debug telemetry all on the same screen. That combination matters because Equity City works best when simulation depth and player legibility arrive together. A city this systemic still has to be operable.

What Comes Next

With this Phase 1 update in place, the next chapter is not just repeating the same baseline claims. It is a product decision about what comes after the current foundation: more player-facing control, richer city communication, and the next layer of living-economy behavior.

That is a good place to be. The city looks more real, the systems are easier to read, and the roadmap can move from proving the foundation to expanding the game.
