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

- Steam appid: 1451200
- Developer: Philosophy♂
- Released: 2020 · Genre: Casual · List price: $10.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $94 to $142 per month (mid $118)
- Opportunity score: $307/month at x2.60 dormancy multiplier
- Est. lifetime owners: 2.0k · Est. lifetime net revenue: $4.7k
- Review sentiment: 34% positive across 73 reviews (67 from Steam purchases)
- Review velocity: 2.0 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 5.5 years
- Studio inactive: no public activity across 1 tracked titles
- Last build shipped 5.2 years ago
- 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 | $214 |
| After VAT / sales tax (-13% blended) | $187 |
| After refunds (-9.5% median) | $169 |
| Net to developer (after Steam 30%) | $118 |

## Monthly review counts, oldest to newest (10 months)

33, 6, 2, 14, 4, 3, 2, 1, 1, 1

## Missed seasonal-sale revenue (modeled)

Skipped 6 Steam seasonal sale window(s) in the last 10 months. Running a -50% discount in those windows is modeled at +$797 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$2.8k to $5.7k (2-4x the trailing net annuity of $1.4k/year). Same error range applies.

## Markets by review language

- japanese: 2% (game NOT localized in this language)
- schinese: 82%
- french: 2% (game NOT localized in this language)
- english: 11% (game NOT localized in this language)
- koreana: 3% (game NOT localized in this language)
- russian: 2% (game NOT localized in this language)

Localization gap: 18% of measured reviews are written in languages the game does not support (top: english). Localizing is likely immediate market expansion.

## 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.
