## Analyst notes (AI-assisted)

Local and online multiplayer dungeon crawler with class-based progression, designed for small groups to play together.

Dungeons of Sundaria generates $1,463/mo residual revenue with 74% positive sentiment, primarily from players valuing its couch co-op feature in a genre starved for local multiplayer options. The title is technically sound at its core but hampered by network stability, split-screen UI scaling, and platforming precision issues that deter repeat engagement. Suitable for a publisher willing to patch stability and UX pain points; revival would require modest studio investment and could unlock stronger word-of-mouth in the co-op community.

- Most realistic play: publishing
- Risk (tech): Network disconnect bugs and split-screen UI scaling issues are cited by multiple reviewers as blocking continued play.
- Risk (multiplayer): Dead or very quiet matchmaking pool; players explicitly cite isolation as a reason to stop playing.
- Risk (market): Developer has posted no updates in 24+ months and studio is listed as fading; code ownership and willingness to re-engage unclear.

What players are asking for:
- Stability patches for online co-op network disconnects
- Split-screen UI scaling and legibility improvements
- Platforming control refinement to reduce drift and missed jumps
- Ongoing content or difficulty balancing to extend endgame

Suggested first moves:
1. Audit code ownership and developer's current legal/contractual standing; confirm ability to patch and redistribute.
2. Prioritize hot-fix for network stability (disconnect handling, server-side reconnect logic) and split-screen UI scaling to lower friction for new trial installs.
3. Conduct soft relaunch on social channels targeting couch co-op communities (local multiplayer Discord, Reddit) with messaging around stability refresh; track post-patch review sentiment and concurrent player uptick over 60 days.

## 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.
