- Steam appid: 3989120
- Developer: TIDERAFT
- Released: 2026 · Genre: Casual · List price: $7.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $750 to $1.1k per month (mid $938)
- Opportunity score: $938/month at x1.00 dormancy multiplier

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.7k |
| After VAT / sales tax (-13% blended) | $1.5k |
| After refunds (-9.5% median) | $1.3k |

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

25, 3

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 2 months. Running a -50% discount in those windows is modeled at +$100 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

- german: 90%
- english: 10%

## 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.
