# Fireboy & Watergirl 2: The Light Temple

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

**Measured on 2026-09-18 02:12 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Steam appid: 5085370
- Developer: Oslo Albet
- Released: 2026 · Genre: Action · List price: $0.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $160 to $240 per month (mid $200)
- Opportunity score: $321/month at x1.60 dormancy multiplier
- Est. lifetime owners: 1.0k · Est. lifetime net revenue: $345
- Review sentiment: 93% positive across 28 reviews (26 from Steam purchases)
- Review velocity: 24.1 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Studio active elsewhere (5 titles tracked), so this one may welcome a partner
- Last build shipped 1 months ago

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $363 |
| After VAT / sales tax (-13% blended) | $316 |
| After refunds (-9.5% median) | $286 |
| Net to developer (after Steam 30%) | $200 |

## Estimated acquisition range

$4.8k to $9.6k (2-4x the trailing net annuity of $2.4k/year). Same error range applies.

## Markets by review language

- russian: 27%
- spanish: 5%
- schinese: 18% (game NOT localized in this language)
- brazilian: 5% (game NOT localized in this language)
- english: 45%

Localization gap: 23% of measured reviews are written in languages the game does not support (top: schinese). 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.
