# 多比大冒险(Doobi's Adventure)

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

- Steam appid: 2193870
- Developer: RainySquare Games
- Released: 2022 · Genre: Action · List price: $2.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $179 to $268 per month (mid $224)
- Opportunity score: $582/month at x2.60 dormancy multiplier
- Est. lifetime owners: 800 · Est. lifetime net revenue: $596
- Review sentiment: 67% positive across 27 reviews (25 from Steam purchases)
- Review velocity: 12.0 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 3.7 years
- Studio inactive: no public activity across 1 tracked titles
- Last build shipped 3.6 years ago
- Store page localized in only 2 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 | $406 |
| After VAT / sales tax (-13% blended) | $353 |
| After refunds (-9.5% median) | $320 |
| Net to developer (after Steam 30%) | $224 |

## Monthly review counts, oldest to newest (2 months)

22, 2

## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 2 months. Running a -50% discount in those windows is modeled at +$224 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

$5.4k to $10.7k (2-4x the trailing net annuity of $2.7k/year). Same error range applies.

## Markets by review language

- french: 4% (game NOT localized in this language)
- german: 4% (game NOT localized in this language)
- english: 8%
- japanese: 8% (game NOT localized in this language)
- schinese: 75% (game NOT localized in this language)

Localization gap: 92% 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 (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.
