# Cafe Master Story

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

- Steam appid: 2427100
- Developer: Kairosoft Co.,Ltd
- Released: 2023 · Genre: Casual · List price: $12.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.2k to $1.7k per month (mid $1.4k)
- Opportunity score: $2.7k/month at x1.90 dormancy multiplier
- Est. lifetime owners: 11.3k · Est. lifetime net revenue: $36.6k
- Review sentiment: 96% positive across 411 reviews (353 from Steam purchases)
- Review velocity: 17.8 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Studio active elsewhere (43 titles tracked), so this one may welcome a partner
- Last build shipped 28 months ago
- Last discounted 3 months ago, 6 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $2.6k |
| After VAT / sales tax (-13% blended) | $2.3k |
| After refunds (-9.5% median) | $2.1k |
| Net to developer (after Steam 30%) | $1.4k |

## Monthly review counts, oldest to newest (24 months)

4, 12, 9, 3, 6, 10, 4, 3, 2, 6, 8, 11, 8, 6, 5, 6, 15, 4, 4, 17, 6, 4, 18, 58

## Missed seasonal-sale revenue (modeled)

Skipped 6 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$3.9k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$34.7k to $69.3k (2-4x the trailing net annuity of $17.3k/year). Same error range applies.

## Markets by review language

- german: 1% (game NOT localized in this language)
- english: 17%

- russian: 0% (game NOT localized in this language)
- spanish: 0% (game NOT localized in this language)

## Analyst notes (AI-assisted)

A cozy business-sim café manager where you brew drinks, cook dishes, hire staff, and decorate your shop to win competitions.

Cafe Master Story is a quiet performer with exceptional community sentiment (96% positive) and steady residual revenue of $1.4k/mo despite minimal marketing push. The title appeals to a demonstrable non-hardcore audience (casual, slow-paced, decorative) with strong retention signals (22–30h average playtime) and active engagement in underserved regions (Chinese and Korean reviews dominate). For a mid-market publisher, this represents a low-risk catalog acquisition or publishing partnership opportunity; Kairosoft's prolific output (17 titles) and operating status suggest capacity for live support or modest localization work.

- Most realistic play: acquisition
- Risk (market): Business-sim category is crowded on Steam; differentiation beyond aesthetic appeal is limited, and viral growth is unlikely without external marketing investment.
- Risk (tech): No developer posts logged recently; unclear whether Kairosoft intends active support or has moved focus to newer titles in their 17-game portfolio.
- Risk (other): Localization gap for German (2.2%) and sparse reviews in Spanish and Russian suggest untapped regional upside but also lower brand awareness in Western markets.

What players are asking for:
- More decoration and customization options for the café space
- Deeper progression systems or late-game goals beyond competitions
- Cross-platform or mobile parity (implied by casual positioning)

Suggested first moves:
1. Acquire title or negotiate revenue-share publishing deal with Kairosoft; validate developer appetite for live updates or content roadmap given their multi-title output model.
2. Audit localization quality and cost for German, Spanish, and Russian, low-hanging fruit to unlock regional spending and review growth in Western markets.
3. A/B test seasonal content drops and cosmetic cosmetics (recipes, décor themes, character skins) against existing $1.4k/mo baseline to model upside in the quiet business-sim niche.

## 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.
