# Memories Off Sousou ~Not always true~

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

- Steam appid: 2604320
- Developer: MAGES. Inc.
- Publisher: Spike Chunsoft Co., Ltd.
- Released: 2025 · Genre: Adventure · List price: $39.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.2k to $1.8k per month (mid $1.5k)
- Opportunity score: $1.5k/month at x1.00 dormancy multiplier
- Est. lifetime owners: 3.0k · Est. lifetime net revenue: $40.8k
- Review sentiment: 73% positive across 128 reviews (95 from Steam purchases)
- Review velocity: 4.5 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 4 months ago
- Studio active elsewhere (31 titles tracked), so this one may welcome a partner
- Last build shipped 18 months ago
- Store page localized in only 3 language(s)
- Last discounted 2 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $2.7k |
| After VAT / sales tax (-13% blended) | $2.4k |
| After refunds (-9.5% median) | $2.2k |
| Net to developer (after Steam 30%) | $1.5k |

## Monthly review counts, oldest to newest (14 months)

58, 3, 2, 1, 0, 1, 1, 1, 1, 16, 3, 3, 2, 2

## Missed seasonal-sale revenue (modeled)

Skipped 6 Steam seasonal sale window(s) in the last 14 months. Running a -50% discount in those windows is modeled at +$11.1k 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: 1% (game NOT localized in this language)
- koreana: 1% (game NOT localized in this language)
- japanese: 10% (game NOT localized in this language)
- schinese: 88%

Localization gap: 12% of measured reviews are written in languages the game does not support (top: japanese). 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.
