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

- Steam appid: 3003300
- Developer: Duoyi Games
- Released: 2025 · Genre: Casual · List price: $3.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $111 to $167 per month (mid $139)
- Opportunity score: $139/month at x1.00 dormancy multiplier
- Est. lifetime owners: 7.1k · Est. lifetime net revenue: $9.5k
- Review sentiment: 82% positive across 2300 reviews (222 from Steam purchases)
- Review velocity: 4.2 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 9 months ago
- Last build shipped 7 months ago
- 90% of reviews come from key activations (excluded from revenue estimates)
- Store page localized in only 3 language(s)
- Last discounted 1 months ago, 6 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $253 |
| After VAT / sales tax (-13% blended) | $220 |
| After refunds (-9.5% median) | $199 |
| Net to developer (after Steam 30%) | $139 |

## Monthly review counts, oldest to newest (23 months)

0, 0, 0, 0, 0, 68, 23, 18, 19, 13, 17, 10, 11, 8, 23, 5, 6, 6, 4, 3, 5, 4, 3

## Missed seasonal-sale revenue (modeled)

Skipped 7 Steam seasonal sale window(s) in the last 23 months. Running a -50% discount in those windows is modeled at +$987 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.
