# Megaton Rainfall

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

- Steam appid: 430210
- Developer: Pentadimensional Games, SL
- Released: 2017 · Genre: Action · List price: $15.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.6k to $2.4k per month (mid $2.0k)
- Opportunity score: $4.2k/month at x2.10 dormancy multiplier
- Est. lifetime owners: 117.5k · Est. lifetime net revenue: $403.8k
- Review sentiment: 72% positive across 2285 reviews (2136 from Steam purchases)
- Review velocity: 23.2 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 8.1 years
- Studio inactive: no public activity across 1 tracked titles
- Last build shipped 7.1 years ago
- Last discounted 1 months ago, 4 sales in the last 12 months
- Proven demand elasticity: x1.8 review velocity during past deep sales

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $3.6k |
| After VAT / sales tax (-13% blended) | $3.1k |
| After refunds (-9.5% median) | $2.8k |
| Net to developer (after Steam 30%) | $2.0k |

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

18, 7, 13, 13, 23, 15, 10, 42, 32, 10, 10, 12, 15, 8, 13, 8, 19, 20, 6, 42, 21, 25, 22, 23

## Estimated acquisition range

$47.8k to $95.5k (2-4x the trailing net annuity of $23.9k/year). Same error range applies.

## Analyst notes (AI-assisted)

A VR-first action game where you play a godlike being defending Earth from alien invasion, built around destruction physics and large-scale combat.

Megaton Rainfall generated $403k lifetime on 117k units at a $15.99 price point, earning $1.99k/mo residually. The core concept (god-sim destruction fantasy) remains commercially viable, but the game suffers from restrictive mission design that contradicts its premise, VR control issues, and no developer communication in 8+ months. For a publisher or studio with VR expertise, the IP and engine foundation could support a ground-up sequel or a focused revival targeting the god-sim niche, which has proven legs elsewhere (Destruction AllStars, Teardown).

- Most realistic play: revival
- Risk (tech): VR controls reportedly non-functional in parts of the tutorial; porting or modernizing the codebase for current headset APIs may require substantial engineering.
- Risk (market): Core complaint is that mission design heavily constrains the 'destroy anything' fantasy; fixing this requires creative redesign, not just patches.
- Risk (other): Developer (Pentadimensional Games, SL) inactive for 8+ months and studio status appears dormant; IP ownership and code access clarity needed before acquisition.

What players are asking for:
- Remove or relax mission restrictions to let players destroy freely and experiment
- Fix VR controls and improve VR experience overall
- Add more varied alien types and combat scenarios beyond repetitive encounters
- Modernize graphics and improve visual clarity

Suggested first moves:
1. Confirm IP ownership and code access status with Pentadimensional Games or estate; if dormant, determine acquisition cost and timeline.
2. Commission a small design audit: identify which restrictions players hate most and sketch a 'sandbox mode' or sequel structure that honors the god-sim fantasy without abandoning structure entirely.
3. Evaluate VR platform parity: test on current SDK versions (Meta Quest 3, SteamVR, PSVR2) to quantify porting effort and identify quickest path to functional VR controls.

## 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.
