# Refence

> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

**Measured on 2026-08-30 10:31 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Est. net residual revenue: $119 to $178 per month (mid $149)
- Opportunity score: $245/month at x1.65 dormancy multiplier
- Est. lifetime owners: 5.6k · Est. lifetime net revenue: $11.3k

|---|---|
| Gross storefront sales | $270 |

| After refunds (-9.5% median) | $213 |

## Monthly review counts, oldest to newest (13 months)

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 13 months. Running a -50% discount in those windows is modeled at +$1.9k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
