# Koi x Shin Ai Kanojo

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

- Steam appid: 2242710
- Developer: Us:track
- Publisher: HIKARI FIELD
- Released: 2023 · Genre: Adventure · List price: $34.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.7k to $2.5k per month (mid $2.1k)
- Opportunity score: $3.9k/month at x1.90 dormancy multiplier
- Est. lifetime owners: 35.0k · Est. lifetime net revenue: $305.1k
- Review sentiment: 90% positive across 1779 reviews (1093 from Steam purchases)
- Review velocity: 9.5 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 3.1 years
- Studio quiet across its whole catalog
- Last build shipped 33 months ago
- Store page localized in only 2 language(s)
- Last discounted 0 months ago, 10 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $3.8k |
| After VAT / sales tax (-13% blended) | $3.3k |
| After refunds (-9.5% median) | $3.0k |
| Net to developer (after Steam 30%) | $2.1k |

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

120, 42, 40, 36, 38, 25, 34, 22, 20, 8, 20, 16, 14, 12, 5, 11, 15, 13, 7, 11, 10, 8, 6, 15

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$8.1k 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

$49.7k to $99.5k (2-4x the trailing net annuity of $24.9k/year). Same error range applies.

## Markets by review language

- english: 0% (game NOT localized in this language)
- schinese: 100%

## Analyst notes (AI-assisted)

A 2023 visual novel with anime-style romance and character-driven storytelling, quietly earning $2,072/mo residual despite minimal developer engagement.

Koi x Shin Ai Kanojo sits in a narrow but real niche: a B-grade VN with 89.6% positive sentiment, $305k lifetime revenue, and persistent monthly cash flow despite zero developer posts in 37 months. The title is dormant rather than dead, sustained almost entirely by discounting (10 promotions in 12 months, currently at -54%). For a publisher or localization specialist, the opportunity is straightforward: the Chinese review base (1,037 of 1,093 Steam reviews) signals untapped regional strength that the original publisher (HIKARI FIELD) is not actively mining. For a revival angle, modest investment in Japanese-to-English localization polish and targeted community engagement could unlock the $3,937/mo opportunity ceiling.

- Most realistic play: publishing
- Risk (market): Visual novel genre saturation and heavy price-elasticity (0.5) mean margin erosion is real; current -54% discount is unsustainable without margin collapse.
- Risk (other): Studio marked 'fading' with one title and 37 months of radio silence; IP ownership and contractual rights to update/remaster may be unclear.
- Risk (tech): Only 2 languages tracked; localization gap of 0.38% suggests incomplete regional support that a stronger publisher could fix, but requires upfront investment.

What players are asking for:
- Official English localization or quality-of-life improvements to existing translation
- Character route DLC or fandisk continuation
- Console ports (Switch, PlayStation)

Suggested first moves:
1. Audit IP ownership and localization rights with HIKARI FIELD; determine if remaster or console port is contractually feasible.
2. Conduct soft re-launch with targeted Chinese regional marketing (Weibo, Bilibili) and a single premium discount event to test price elasticity above current floor.
3. Commission a cost estimate for English script review and console porting to validate the $3,937/mo uplift scenario.

## 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.
