# 她毕业了 So Long, My Youth

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

- Steam appid: 2186270
- Developer: 煎饼工作室 PanCakeStudio
- Released: 2025 · Genre: Casual · List price: $1.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $71 to $107 per month (mid $89)
- Opportunity score: $133/month at x1.50 dormancy multiplier
- Est. lifetime owners: 896 · Est. lifetime net revenue: $598
- Review sentiment: 67% positive across 54 reviews (28 from Steam purchases)
- Review velocity: 5.3 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 11 months ago
- Last build shipped 11 months ago
- 48% of reviews come from key activations (excluded from revenue estimates)
- Store page localized in only 1 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 | $162 |
| After VAT / sales tax (-13% blended) | $141 |
| After refunds (-9.5% median) | $127 |
| Net to developer (after Steam 30%) | $89 |

## Monthly review counts, oldest to newest (6 months)

26, 5, 0, 0, 0, 1

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 6 months. Running a -50% discount in those windows is modeled at +$50 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.
