# Rift Riff

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

- Steam appid: 2800900
- Developer: Adriaan de Jongh
- Released: 2025 · Genre: Action · List price: $12.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $450 to $675 per month (mid $563)

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

|---|---|
| Gross storefront sales | $1.0k |
| After VAT / sales tax (-13% blended) | $889 |
| After refunds (-9.5% median) | $804 |

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

190, 28, 26, 17, 8, 37, 11, 8, 10, 6, 3, 6, 7, 6, 3

## 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 +$2.7k 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: 2%
- koreana: 0%
- russian: 3%
- spanish: 2%
- japanese: 1%
- brazilian: 1%
- french: 3%
- english: 84%
- schinese: 2%

## 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.
