- Steam appid: 3361340
- Developer: Three River Games (3RG)
- Released: 2025 · Genre: Casual · List price: $9.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $190 to $285 per month (mid $237)
- Opportunity score: $237/month at x1.00 dormancy multiplier
- Est. lifetime owners: 2.7k · Est. lifetime net revenue: $9.1k
- Review sentiment: 92% positive across 95 reviews (85 from Steam purchases)
- Review velocity: 2.8 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 11 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 | $431 |
| After VAT / sales tax (-13% blended) | $375 |
| After refunds (-9.5% median) | $339 |
| Net to developer (after Steam 30%) | $237 |

## Monthly review counts, oldest to newest (15 months)

36, 3, 5, 4, 1, 2, 3, 5, 8, 4, 4, 4, 2, 2, 1

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 15 months. Running a -50% discount in those windows is modeled at +$502 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 (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.
