# Stay: Your Forever Pet!

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

- Steam appid: 4385270
- Developer: Windup Minds
- Released: 2026 · Genre: Casual · List price: $12.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $5.0k to $7.4k per month (mid $6.2k)
- Opportunity score: $6.2k/month at x1.00 dormancy multiplier
- Est. lifetime owners: 1.9k · Est. lifetime net revenue: $8.1k
- Review sentiment: 99% positive across 67 reviews (58 from Steam purchases)
- Review velocity: 57.0 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 1 months ago
- Last build shipped 1 months ago
- Store page localized in only 1 language(s)
- Last discounted 1 months ago, 1 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $11.3k |
| After VAT / sales tax (-13% blended) | $9.8k |
| After refunds (-9.5% median) | $8.9k |
| Net to developer (after Steam 30%) | $6.2k |

## Monthly review counts, oldest to newest (1 months)

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 1 months. Running a -50% discount in those windows is modeled at +$3.1k 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

- english: 97% (game NOT localized in this language)
- koreana: 2% (game NOT localized in this language)
- spanish: 2% (game NOT localized in this language)

Localization gap: 100% of measured reviews are written in languages the game does not support (top: english). 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.
