- Publisher: DMM GAMES
- Released: 2020 · Genre: Adventure · List price: $39.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.4k to $2.1k per month (mid $1.8k)
- Opportunity score: $2.7k/month at x1.50 dormancy multiplier
- Est. lifetime owners: 39.8k · Est. lifetime net revenue: $341.7k
- Review sentiment: 93% positive across 1381 reviews (1325 from Steam purchases)

- Store page localized in only 3 language(s)
- Last discounted 1 months ago, 7 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 | $3.3k |
| After VAT / sales tax (-13% blended) | $2.8k |
| After refunds (-9.5% median) | $2.6k |
| Net to developer (after Steam 30%) | $1.8k |

## Estimated acquisition range

$43.0k to $86.0k (2-4x the trailing net annuity of $21.5k/year). Same error range applies.

## Analyst notes (AI-assisted)

A story-driven JRPG adventure from AQUAPLUS set in a fantasy world with tactical combat and branching narrative choices.

Mask of Deception holds $341.7k lifetime net revenue across 39,750 units sold and currently generates $1,790/mo residual income, well above the platform's typical dormant-catalog floor. The 92.7% positive review rate and 67-month platform lifetime suggest a dedicated franchise fanbase with genuine engagement; reviews describe the narrative and character work as standout. This is a quiet earner for DMM GAMES' backlist, suitable for portfolio acquisition if VN/JRPG expansion is a strategic priority, but carries the risk that its IP and localization depend entirely on AQUAPLUS' willingness to support or license further.

- Most realistic play: acquisition
- Risk (market): Narrative-driven JRPGs face declining mainstream discoverability on Steam; the 92.7% positive sentiment does not reflect 7 sales in the past 12 months, suggesting strong word-of-mouth cannot overcome algorithmic inertia.
- Risk (tech): High elasticity (1.76) means price cuts may drive short-term volume but erode margin; the last deep sale occurred 1.4 months ago, implying discount fatigue or algorithmic suppression.
- Risk (other): AQUAPLUS operates only 4 titles on Steam; future localization, ports, or sequel support depend on their resource allocation and publisher priority, both of which appear limited.

What players are asking for:
- More visible Final Strike attack animations across the campaign, not just endgame
- Continued franchise localization and sequel support
- Quality-of-life improvements to pacing in early chapters

Suggested first moves:
1. Audit AQUAPLUS' IP portfolio and current licensing terms with DMM GAMES to establish whether sequel or spin-off IP is available or exclusive.
2. Model a limited regional price experiment (e.g., tier pricing in emerging markets) to test whether current $39.99 pricing is the ceiling or a result of publisher conservatism.
3. Engage AQUAPLUS directly on localization roadmap for the Utawarerumono franchise; if they lack bandwidth, a publishing or co-development partnership could unlock dormant revenue from untranslated entries in the series.

## 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.
