## Filtering the full set

This page shows the top 100. The complete, filterable set is the JSON API:

`https://residualplay.com/api/v1/radar?page=1&per=50`

Parameters: `q` (free text over name, developer, publisher), `genre`, `grade` (A|B|C|D), `status` (ghost = inactive studio, fading = quiet, operating = active), `dormant=1`, `opp_min` / `opp_max` (USD per month), `year_min` / `year_max`, `sent_min` (positive review %), `owners_min`, `no_discount=1` (no discount in 24 months), `proven=1` (proven price elasticity), `stale_build=1` (no build in 36 months), `loc_gap=1` (10%+ of reviews in unsupported languages), `sort` (opportunity|residual|rpm|silence).

The same query returns CSV at `https://residualplay.com/api/v1/radar.csv`.

## Deal grades

- A: dormant with $5k+/month of opportunity
- B: dormant with $300+/month
- C: dormant, or $1k+/month
- D: tracked, low signal

## How these numbers are built

1. Units: Steam-purchase reviews only (key activations excluded) times a release-cohort multiplier, 40-75x depending on release year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by the developers themselves; older cohorts follow the published Boxleiter tables.
2. Price: an effective price that accounts for lifetime discount depth and Steam regional pricing, not the US list price.
3. Net: VAT (~13%), refunds (~9.5%) and Steam's 30% cut are removed, so roughly 55% of gross reaches the developer. Every dollar figure on this site is net to the developer.

Estimates carry a +/-30-50% error range per title and are tighter in aggregate. They are built from public signals only (Steam reviews and review history, store metadata, developer announcements, price and discount history, public build dates) and are directional, not financial statements.

Famous titles and actively operating major publishers are excluded by design: this is the long tail nobody is watching.
