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

**Measured on 2026-09-05 12:12 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Steam appid: 3421430
- Developer: RoyalJellySoftware
- Released: 2025 · Genre: Action · List price: $4.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $77 to $116 per month (mid $97)
- Opportunity score: $126/month at x1.30 dormancy multiplier
- Est. lifetime owners: 1.5k · Est. lifetime net revenue: $2.5k
- Review sentiment: 100% positive across 40 reviews (37 from Steam purchases)
- Review velocity: 2.3 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 2 months ago
- Store page localized in only 1 language(s)
- Last discounted 2 months ago, 2 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $176 |
| After VAT / sales tax (-13% blended) | $153 |
| After refunds (-9.5% median) | $138 |
| Net to developer (after Steam 30%) | $97 |

## Monthly review counts, oldest to newest (16 months)

9, 4, 3, 1, 1, 1, 1, 2, 1, 1, 2, 1, 3, 3, 1, 3

## Missed seasonal-sale revenue (modeled)

Skipped 7 Steam seasonal sale window(s) in the last 16 months. Running a -50% discount in those windows is modeled at +$335 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## 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.
