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

- Steam appid: 2603020
- Developer: Abylight Barcelona
- Publisher: Abylight Studios
- Released: 2024 · Genre: Indie · List price: $24.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $3.4k to $5.1k per month (mid $4.3k)
- Opportunity score: $4.3k/month at x1.00 dormancy multiplier
- Est. lifetime owners: 31.6k · Est. lifetime net revenue: $230.5k
- Review sentiment: 84% positive across 1063 reviews (986 from Steam purchases)
- Review velocity: 23.3 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 5 months ago
- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 6 months ago
- Last discounted 1 months ago, 8 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $7.7k |
| After VAT / sales tax (-13% blended) | $6.7k |
| After refunds (-9.5% median) | $6.1k |
| Net to developer (after Steam 30%) | $4.3k |

## Monthly review counts, oldest to newest (22 months)

310, 82, 50, 39, 15, 25, 50, 95, 20, 18, 21, 13, 10, 52, 27, 26, 12, 48, 23, 25, 13, 19

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 22 months. Running a -50% discount in those windows is modeled at +$12.9k 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

- schinese: 13%
- english: 51%
- koreana: 2% (game NOT localized in this language)
- japanese: 1%
- brazilian: 2%
- french: 8%
- german: 8%
- russian: 6%
- spanish: 10%

## 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.
