## Analyst notes (AI-assisted)

OPUS: The Day We Found Earth is a short narrative adventure game about discovering Earth's history, originally designed as a mobile experience.

This indie title has quietly accrued $292k lifetime revenue on modest ~91k units with a steady 87% positive rating and 12 reviews/month residual activity. At $980/mo in current earnings, it's not a growth story, but the strong attach rate to players who complete it (9+ hours logged by engaged fans), cross-platform pedigree (mobile-to-PC port), and recurring discounting pattern suggest dormant IP with indie-licensing or bundle-play potential rather than standalone acquisition value. The core friction is content length and price positioning: players love the aesthetic but resent the $14.99 ask for a 1-2 hour experience.

- Most realistic play: licensing
- Risk (market): Strong price-sensitivity signals (75% max discount used, players explicitly cite $14.99 as unjustified for playtime) limit full-price positioning; franchise extension or bundle inclusion may be only viable monetization path.
- Risk (tech): 57 months since original build and 44 months since last developer post suggests codebase stability but no active maintenance; mobile-to-PC port quality issues may resurface if ported again.
- Risk (other): Mobile version reportedly implemented as idle game (different gameplay loop); rights or code separation unclear, complicating multi-platform strategy.

What players are asking for:
- Longer story or more expansive lore (players cite lack of character attachment)
- Price reduction or clear justification for $14.99 tag relative to playtime
- Gameplay depth beyond aesthetic and narrative (currently seen as passive/linear)

Suggested first moves:
1. Verify mobile IP status and code ownership (original idle game vs. PC port) to assess rights clearance for revival or multi-platform bundle licensing.
2. Model bundle scenario (e.g., Story/Adventure subscription, Cozy Games collections) where $14.99 friction disappears and $980/mo baseline becomes upside via volume.
3. Conduct light creator outreach (streamer/YouTube) using discount keys to test whether indie darling narrative (solo developer, cross-platform heritage, visual novelty) can drive seasonal spikes above current 12-18 unit/month velocity.

## 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.
