# AIR

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

- Steam appid: 2983250
- Developer: VISUAL ARTS/Key
- Publisher: VISUAL ARTS
- Released: 2025 · Genre: Adventure · List price: $29.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $5.2k to $7.7k per month (mid $6.5k)
- Opportunity score: $8.7k/month at x1.35 dormancy multiplier
- Est. lifetime owners: 19.3k · Est. lifetime net revenue: $193.7k
- Review sentiment: 98% positive across 829 reviews (602 from Steam purchases)
- Review velocity: 25.7 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 14 months
- Studio active elsewhere (6 titles tracked), so this one may welcome a partner
- Last build shipped 14 months ago
- Store page localized in only 3 language(s)
- Last discounted 1 months ago, 6 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $11.7k |
| After VAT / sales tax (-13% blended) | $10.2k |
| After refunds (-9.5% median) | $9.2k |
| Net to developer (after Steam 30%) | $6.5k |

## Monthly review counts, oldest to newest (17 months)

201, 30, 17, 13, 32, 19, 7, 23, 64, 20, 17, 15, 16, 25, 19, 18, 61

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 17 months. Running a -50% discount in those windows is modeled at +$29.0k 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

$154.9k to $309.7k (2-4x the trailing net annuity of $77.4k/year). Same error range applies.

## Markets by review language

- japanese: 7% (game NOT localized in this language)
- schinese: 74%
- french: 0% (game NOT localized in this language)
- brazilian: 0% (game NOT localized in this language)
- german: 0% (game NOT localized in this language)
- english: 16%
- koreana: 1% (game NOT localized in this language)
- russian: 2% (game NOT localized in this language)
- spanish: 0% (game NOT localized in this language)

Localization gap: 10% of measured reviews are written in languages the game does not support (top: japanese). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

AIR is a 2025 Steam port of Key's 2000 visual novel, a foundational emotional narrative game exploring interconnected stories across five character routes.

This title is a canonical work in the visual novel canon with exceptional player sentiment (98% positive) and modest but consistent residual revenue ($6.5k/mo mid, $8.7k/mo upside). The port is recent (14 months live), freshly discounted, and driving 25 reviews/mo. However, lifetime revenue of $194k on 19k units suggests a small, devoted audience with limited mainstream crossover. Most realistic play is watch-and-wait for IP licensing opportunities tied to the wider Key catalog, or a targeted localization push into underserved languages (Japanese localization gap noted at 10%).

- Most realistic play: watch
- Risk (market): Visual novel genre has narrow mainstream appeal; peak player engagement occurred in 2000s anime/otaku circles, limiting franchise extension outside dedicated communities.
- Risk (tech): Port is 14 months old with no developer communication since launch; long-term technical support and platform parity maintenance unclear.
- Risk (other): Steam version removes adult content present in original 2000 release, which may constrain licensing/revival narratives around 'complete' editions.

What players are asking for:
- Restoration or acknowledgment of original adult content (present in reviews as spoiler discussion)
- Additional Key visual novel ports to Steam (franchise bundling implied by multi-route comparisons)
- Deck verification and modern OS support parity updates

Suggested first moves:
1. Audit Key IP catalog (developer has 3 titles; establish if AIR, Clannad, Kanon rights stack or fragment across regional publishers) to model bundled Steam release strategy.
2. Validate Japanese localization gap (10% loc gap, Japanese reviews 38/829): A2A localization spend to capture untapped Japan/Asia steam markets where visual novel enthusiasm remains higher.
3. Monitor 12-month discount velocity (6 promotions, max 65% off, most recent 0.8 months ago): Establish if current pricing ($30) holds or requires dynamic bundling with other Key titles to lift units without margin erosion.

Generated 2026-08-20 from public signals and player reviews. Directional, not diligence.

## 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.
