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

- Steam appid: 1848450
- Developer: Checkmaty
- Released: 2022 · Genre: Action · List price: $4.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $817 to $1.2k per month (mid $1.0k)
- Opportunity score: $2.1k/month at x2.10 dormancy multiplier
- Est. lifetime owners: 134.2k · Est. lifetime net revenue: $167.0k
- Review sentiment: 96% positive across 4388 reviews (4194 from Steam purchases)
- Review velocity: 32.8 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 3.9 years
- Studio inactive: no public activity across 1 tracked titles
- Last build shipped 3.9 years ago
- Last discounted 1 months ago, 9 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.9k |
| After VAT / sales tax (-13% blended) | $1.6k |
| After refunds (-9.5% median) | $1.5k |
| Net to developer (after Steam 30%) | $1.0k |

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

41, 41, 46, 46, 50, 53, 42, 45, 22, 50, 53, 39, 37, 43, 42, 68, 36, 35, 23, 43, 29, 22, 36, 44

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$3.4k 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

$24.5k to $49.0k (2-4x the trailing net annuity of $12.3k/year). Same error range applies.

## Analyst notes (AI-assisted)

Nightmare of Decay is a short-form first-person survival horror title directly inspired by Resident Evil 1, built by solo developer Checkmaty and released in 2022.

Despite dormant developer activity and a single-title studio, this game maintains a 95.7% positive rating and generates $1,021/mo in residual revenue on $4.99 sticker price. The consistent play-through completion (2-4 hours) and strong RE1 nostalgia appeal suggest a stable, if modest, audience. Interest lies not in acquisition but in understanding why a low-visibility indie horror title sustains such clean fundamentals, and whether dormancy reflects burnout or successful long-tail monetization.

- Most realistic play: watch
- Risk (other): Developer has posted no updates in 46+ months; studio status flagged as inactive, raising questions about support, patching, and any potential for post-launch content or platform updates.
- Risk (market): Player feedback consistently notes the game's appeal is primarily to RE1 purists; value proposition is opaque for players without franchise nostalgia.
- Risk (other): Spanish localization gap (5.3%) and 4.4% key-reseller leakage suggest modest international reach and potential margin dilution, though not critical at this price tier.

What players are asking for:
- Slower movement speed and more fluid controls
- Added atmospheric music or clearer audio design guidance
- Additional post-game content or extended campaign modes

Suggested first moves:
1. Validate whether the $1,021/mo residual is driven by seasonal sales surges, algorithmic discounting, or organic tail traffic; confirm velocity data for anomalies in the last 12 months.
2. Interview Checkmaty or review any public statements on studio status to determine if dormancy reflects choice (successful passive income) or exit; clarify any IP claims or licensing constraints.
3. Assess localization ROI: Spanish gap suggests an easy win for a publisher seeking to boost international uptake without heavy creative investment; A/B test a cheap regional marketing push.

## 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.
