# X-Plane 11

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

- Steam appid: 269950
- Developer: Laminar Research
- Released: 2017 · Genre: Simulation · List price: $29.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $12.8k to $19.2k per month (mid $16.0k)
- Opportunity score: $33.6k/month at x2.10 dormancy multiplier
- Est. lifetime owners: 1.1M · Est. lifetime net revenue: $6.8M
- Review sentiment: 93% positive across 20218 reviews (19116 from Steam purchases)
- Review velocity: 99.3 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 4.3 years
- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 5.2 years ago

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $29.1k |
| After VAT / sales tax (-13% blended) | $25.3k |
| After refunds (-9.5% median) | $22.9k |
| Net to developer (after Steam 30%) | $16.0k |

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

160, 112, 106, 115, 172, 155, 107, 119, 74, 76, 80, 141, 109, 81, 106, 98, 133, 136, 94, 119, 91, 63, 99, 130

## Estimated acquisition range

$384.2k to $768.4k (2-4x the trailing net annuity of $192.1k/year). Same error range applies.

## Markets by review language

- german: 4%
- english: 53%
- koreana: 2% (game NOT localized in this language)
- russian: 13% (game NOT localized in this language)
- brazilian: 9% (game NOT localized in this language)
- french: 3%
- spanish: 6%
- japanese: 0% (game NOT localized in this language)
- schinese: 11% (game NOT localized in this language)

Localization gap: 35% of measured reviews are written in languages the game does not support (top: russian). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

X-Plane 11 is a high-fidelity flight simulator that prioritizes realistic aerophysics and runs on modest hardware, competing directly with Microsoft Flight Simulator.

X-Plane 11 generates $16,008/mo in residual revenue on a six-year-old codebase with 93% positive reviews and a 1.05M+ unit installed base, yet shows zero velocity decay and minimal developer engagement in 51+ months. The title's independence from licensed aircraft or airport IP, bundled with an active third-party add-on ecosystem (Zibo 737, Navigraph) and cross-platform reach, makes it a candidate for quiet acquisition by a larger sim publisher seeking long-tail cash flow and a low-overhead catalog title. However, X-Plane 12 (released 2023) may already be cannibalizing sales; verify upgrade funnel before committing.

- Most realistic play: acquisition
- Risk (market): X-Plane 12 launched in late 2023; X-Plane 11 may face accelerating player migration and reduced support momentum.
- Risk (tech): Zero discounting history and elasticity of -1 suggest inelastic demand, but 62+ months without a major build update raises questions about technical debt and future maintenance costs.
- Risk (other): Developer Laminar Research owns both X-Plane 11 and X-Plane 12 and is actively operating; outright acquisition unlikely unless founders exit or IP is divested.

What players are asking for:
- Updated navigation data (Navigraph subscription workaround mentioned; players want native integration)
- Improved controller/gamepad support (noted as unintuitive relative to keyboard/mouse)
- Better on-screen tooltips and settings discoverability (steep learning curve cited)
- Expanded default aircraft and airport variety without mandatory add-ons

Suggested first moves:
1. Obtain sales and install data for X-Plane 12 to quantify cannibalization and estimate sustainable residual for X-Plane 11 post-2025.
2. Map the add-on ecosystem (Zibo, Navigraph, payware aircraft authors) to assess IP entanglement and revenue share; determine if third-party add-on licensing can be renegotiated under new ownership.
3. Conduct outreach to Laminar Research founders to clarify long-term support and pricing strategy for X-Plane 11; assess appetite for sale, licensing deal, or co-publishing arrangement that preserves indie control.

## 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.
