# Project Silverfish

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

- Steam appid: 2941710
- Developer: Siris Pendrake
- Released: 2025 · Genre: Action · List price: $29.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $18.8k to $28.3k per month (mid $23.5k)
- Opportunity score: $23.5k/month at x1.00 dormancy multiplier
- Est. lifetime owners: 98.5k · Est. lifetime net revenue: $990.2k
- Review sentiment: 93% positive across 3284 reviews (3077 from Steam purchases)
- Review velocity: 93.7 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 2 months ago
- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 6 months ago
- Store page localized in only 1 language(s)
- Last discounted 1 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $42.7k |
| After VAT / sales tax (-13% blended) | $37.2k |
| After refunds (-9.5% median) | $33.7k |
| Net to developer (after Steam 30%) | $23.5k |

## Monthly review counts, oldest to newest (14 months)

332, 726, 382, 227, 306, 210, 188, 193, 90, 74, 66, 47, 103, 182

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 14 months. Running a -50% discount in those windows is modeled at +$183.7k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- japanese: 1% (game NOT localized in this language)
- brazilian: 1% (game NOT localized in this language)
- french: 1% (game NOT localized in this language)
- german: 1% (game NOT localized in this language)
- russian: 5% (game NOT localized in this language)
- schinese: 1% (game NOT localized in this language)
- english: 91% (game NOT localized in this language)
- koreana: 0% (game NOT localized in this language)
- spanish: 0% (game NOT localized in this language)

Localization gap: 100% 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.
