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

**Measured on 2026-08-29 22:23 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Steam appid: 3749320
- Developer: 初域游戏
- Released: 2026 · Genre: Casual · List price: $10.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $110.0k to $165.0k per month (mid $137.0k)
- Opportunity score: $247.0k/month at x1.80 dormancy multiplier
- Est. lifetime owners: 60.5k · Est. lifetime net revenue: $223.0k
- Review sentiment: 98% positive across 1537 reviews (1513 from Steam purchases)
- Review velocity: 1491.3 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 0 months ago
- Last build shipped 0 months 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 | $248.7k |
| After VAT / sales tax (-13% blended) | $216.4k |
| After refunds (-9.5% median) | $195.8k |
| Net to developer (after Steam 30%) | $137.0k |

## Estimated acquisition range

$3.3M to $6.6M (2-4x the trailing net annuity of $1.6M/year). Same error range applies.

## Markets by review language

- english: 0% (game NOT localized in this language)
- schinese: 100% (game NOT localized in this language)
- brazilian: 0% (game NOT localized in this language)

Localization gap: 100% of measured reviews are written in languages the game does not support (top: schinese). Localizing is likely immediate market expansion.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. 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.
