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

- Steam appid: 3604140
- Developer: Sw33tSaNity
- Released: 2025 · Genre: Indie · List price: $1.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $67 to $100 per month (mid $83)
- Opportunity score: $154/month at x1.85 dormancy multiplier
- Est. lifetime owners: 800 · Est. lifetime net revenue: $534
- Review sentiment: 76% positive across 25 reviews (25 from Steam purchases)
- Review velocity: 5.0 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 17 months
- Studio quiet across its whole catalog
- Last build shipped 17 months ago
- Store page localized in only 2 language(s)
- No Steam discount in 4.0 years (deepest tracked: -0%)

## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $151 |
| After VAT / sales tax (-13% blended) | $132 |
| After refunds (-9.5% median) | $119 |
| Net to developer (after Steam 30%) | $83 |

## Monthly review counts, oldest to newest (5 months)

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 5 months. Running a -50% discount in those windows is modeled at +$158 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 (Boxleiter method, 20-75x by year). 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.
