# Eros Memories: The Lewd Way to Save the World

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

**Measured on 2026-09-01 19:12 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Developer: S3xyGames
- Publisher: HENTAI Plan
- Released: 2026 · Genre: Casual · List price: $14.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $2.4k to $3.6k per month (mid $3.0k)

## Why it's flagged

- Last build shipped 0 months ago
- Store page localized in only 4 language(s)

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $5.4k |
| After VAT / sales tax (-13% blended) | $4.7k |
| After refunds (-9.5% median) | $4.3k |
| Net to developer (after Steam 30%) | $3.0k |

## Markets by review language

- english: 11%
- koreana: 16% (game NOT localized in this language)
- japanese: 5%
- schinese: 68%

Localization gap: 16% of measured reviews are written in languages the game does not support (top: koreana). Localizing is likely immediate market expansion.

## 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.
