**Measured on 2026-09-04 04:10 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

## Estimated acquisition range

$41.8k to $83.5k (2-4x the trailing net annuity of $20.9k/year). Same error range applies.

## Markets by review language

- german: 8% (game NOT localized in this language)
- english: 29%

Koikata: How Our Love Grows is a visual novel romance title from Kagami Games featuring school-life dating sim mechanics and character-driven storytelling.

This indie moege occupies a narrow but durable niche: 96% positive reception, steady low-four-figure monthly residuals, and a small but engaged community primarily in Asia and Germany. The title is production-constrained rather than commercially failed, and its localization quality and character work have genuine appeal. For a publisher seeking catalog depth in visual novels or a developer exploring revival publishing, it offers modest but reliable cashflow with minimal ongoing support burden. Acquisition plays are limited by the indie studio's singular title, but publishing partnerships or localization expansion merit evaluation.

- Most realistic play: publishing
- Risk (market): Visual novel market is niche, geographically fragmented, and sensitive to translation quality; player base remains small and unlikely to scale without major localization push or bundling.
- Risk (tech): No workshop support, cards, or community features; limited engagement levers for live operation or viral growth.
- Risk (other): Developer appears inactive (no recorded posts or updates in available window); revival or expansion would require direct studio coordination or IP acquisition.

What players are asking for:
- More background variety and environmental scene depth to support narrative branching
- Localization terminology consistency refinement (already in progress per dev notes)
- Sequel or spin-off content featuring the ensemble cast

Suggested first moves:
1. Audit localization backlog and estimate cost/lift for German and Simplified Chinese refinement; even partial correction could unlock regional uplift.
2. Model bundling scenarios (visual novel collections, platform exclusivity, subscription inclusion) to test elasticity; current elasticity estimate suggests modest price sensitivity.
3. Contact Kagami Games to explore publishing partnership, IP representation rights, or developer acquisition terms; single-title studio may be acquisition-friendly if studio status and development capacity are clarified.

## 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.
