- Developer: Grounding Inc.
- Publisher: Bandai Namco Entertainment Inc.
- Released: 2024 · Genre: Casual · List price: $9.99
- Deal grade: C (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: $2.1k/month at x1.00 dormancy multiplier

## 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 (21 months)

1224, 271, 86, 74, 53, 36, 45, 36, 35, 154, 65, 29, 30, 84, 51, 38, 36, 19, 26, 28, 27

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 21 months. Running a -50% discount in those windows is modeled at +$48.9k 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

- brazilian: 5% (game NOT localized in this language)
- german: 1%
- russian: 6% (game NOT localized in this language)
- spanish: 5%
- french: 2%
- english: 66%
- koreana: 3% (game NOT localized in this language)
- japanese: 8%
- schinese: 4% (game NOT localized in this language)

Localization gap: 18% of measured reviews are written in languages the game does not support (top: russian). 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.
