Why now?

The Show HN launch drew 914 points, which shows the premise — SimCity-style play built around the permit process — is memorable and shareable right now. The autocomplete signal (9) suggests steady search interest in urban planning and city-building terms. But this is a single viral moment, not a proven market: there are no download numbers, no recurring usage data, and no evidence of demand beyond one launch spike.

The gap

City-building games rarely model bureaucracy, zoning, and permits as the core mechanic. This project shows that framing can get attention, and the urban planning enthusiast niche is underserved. Demand for a full product is not yet proven — the only evidence is one HN post's points and modest autocomplete interest.

Main competitor

The broader city-builder genre (SimCity, Cities: Skylines) and free browser city games. The 'permits as gameplay' angle has no established competitor, but that also means no validated category.

Execution plan

1. Ship a tight, polished browser build with a clear win/lose loop (approve, deny, appeal, budget) and shareable end-of-run results, so the HN spike converts into repeat plays.
2. Add a level/scenario pipeline: real-world-inspired zoning puzzles (NIMBY disputes, transit corridors, historic districts) so content, not just the premise, drives retention.
3. Instrument basic analytics (plays, session length, level completion) to test whether the viral interest turns into retention before investing further.
4. Build a lightweight community loop — shareable scenario links and a way for players to submit their own permit puzzles.
5. Only after retention is proven, explore monetization; keep the core free to preserve the shareable hook.

Monetization

Unproven. The signals show no revenue path — no downloads, no pricing, no ad or IAP data. Realistic options to test later are a premium level pack or a 'supporter' tier for extra scenarios, or non-intrusive ads on the free browser build. Treat any revenue as speculative until retention data exists.
