# S.T.A.L.K.E.R.: Shadow of Chernobyl

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

- Steam appid: 4500
- Developer: GSC Game World
- Released: 2007 · Genre: Action · List price: $19.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $10.0k to $15.0k per month (mid $12.5k)
- Opportunity score: $29.4k/month at x2.35 dormancy multiplier
- Est. lifetime owners: 2.8M · Est. lifetime net revenue: $12.2M
- Review sentiment: 95% positive across 48086 reviews (37929 from Steam purchases)
- Review velocity: 116.5 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 15 months
- Studio active elsewhere (16 titles tracked), so this one may welcome a partner
- Last build shipped 3.2 years ago
- No Steam discount in 1.7 years (deepest tracked: -75%)
- Proven demand elasticity: x4.8 review velocity during past deep sales

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $22.7k |
| After VAT / sales tax (-13% blended) | $19.8k |
| After refunds (-9.5% median) | $17.9k |
| Net to developer (after Steam 30%) | $12.5k |

## Monthly review counts, oldest to newest (24 months)

516, 352, 489, 1146, 1273, 525, 265, 278, 250, 351, 135, 125, 137, 106, 117, 202, 126, 117, 104, 103, 122, 153, 114, 103

## Missed seasonal-sale revenue (modeled)

Skipped 11 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$448.4k net in total, assuming a unit uplift of x4.8 taken from this game's own sale history. Same ±30-50% error range applies.

## Estimated acquisition range

$300.3k to $600.7k (2-4x the trailing net annuity of $150.2k/year). Same error range applies.

## Analyst notes (AI-assisted)

S.T.A.L.K.E.R.: Shadow of Chernobyl is a 2007 post-apocalyptic FPS set in an alternate Chernobyl exclusion zone, built on immersive atmosphere and emergent survival gameplay.

This flagship title has generated $12.2M lifetime net revenue from 2.8M units sold and currently earns $12.5/mo residual, with 94.7% positive reviews and a 116.5 reviews/month baseline indicating sustained organic discovery. The game sits dormant but active: no major discount in 19+ months, no dev communication in 15+ months, yet a thriving mod ecosystem (Radiophobia 3 cited as transformative) and franchise momentum from S.T.A.L.K.E.R. 2 (2024) create a unique window. For a publisher, this is a low-risk catalog hold with untapped potential in localization (5.6% gap, especially Brazilian Portuguese), seasonal promotions, and cross-franchise bundling.

- Most realistic play: publishing
- Risk (tech): Engine is 17+ years old; compatibility and platform support (VR, new OS builds) may require ongoing maintenance.
- Risk (market): Player base is nostalgic early-adopter skew; mainstream appeal is explicitly low per case file, limiting growth ceiling.
- Risk (other): Developer GSC Game World was historically affected by geopolitical disruption; current operational status is stable but historical context may complicate future acquisition or IP licensing.

What players are asking for:
- Bug fixes and radiation/stamina system rebalancing for late-game progression
- Modding documentation and official mod support infrastructure
- Localization completion, especially Brazilian Portuguese and Chinese
- Performance/compatibility patches for modern OS and display hardware

Suggested first moves:
1. Audit mod ecosystem (Radiophobia 3, Community Atmospheric Suits, etc.) and explore tiers of official curation or revenue-share model to formalize the mod-extension value proposition.
2. Run A/B discount tests and regional pricing strategies (Brazil +10-15% visibility, China bundle with localized tier) to test the $29.4k/mo opportunity ceiling without cannibilizing full-price discovery.
3. Evaluate one-pass bug triage and stamina rebalance to unlock completionist cohort and reduce negative review friction; low engineering cost relative to franchise goodwill.

## 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.
