§0 Executive Summary
Conclusion: Experience's next move should be a "Japanese Horror DRPG" — the fusion of Death Mark (Spirit Hunter) × DRPG.
- Wizardry Daphne (3 million DL) proved that "DRPGs without story will no longer be chosen"
- The greatest weakness of Experience's DRPGs is thin storytelling; the greatest untapped asset is Death Mark's narrative power
- "Japanese Horror DRPG" does not exist anywhere in the world market. It is a blue ocean reachable with internal resources alone

§1 Situation: Experience's 20 Years and Current Position
Who Is Experience Inc.?
Founded in 2007 by Hajime Chikami and Motoya Ataka after the collapse of Michaelsoft. From the "Team Muramasa" era onward, they have consistently made DRPGs — the longest-running DRPG-specialized developer in Japan. 15 employees, ¥3 million capital. For 20 years, they have sustained the DRPG market through craftsmanship without relying on major capital.

| Generation XTH (1-3) | 2007-10 | PC | Doujin-scale origins. Official site mail-order only |
| Students of Round | 2010-13 | PC→X360→PSP | Console debut. Start of Kadokawa partnership |
| Demon Gaze | 2013 | PS Vita | Minor hit. Jim Sterling 4.5/5. Established beginner-friendly DRPG |
| Demon Gaze 2 | 2017 | Vita/PS4 | Inherited predecessor's reputation. Vita market decline |

Current State: Three Lines Running Simultaneously
The company president stated on March 4, 2026: "Demon Kill Demon development is nearly complete. Starting next month, we move to the next project. Death Mark reboot goes into full production. Need to decide which DRPG to make next."
- Demon Kill Demon (5/28 launch — final polish)
- Death Mark Reboot (10th anniversary — crowdfunding success — 2027 release)
- Next DRPG (planning stage — undecided)
This report serves decision-making for line 3.
§2 Complication: The Fans Have Spoken — Recurring Praise and Recurring Complaints
Strengths: What Nobody Can Replicate
① Peak Comfort System Design
"I wish every DRPG had combat this fast" — repeated across Amazon reviews. High-speed combat, auto-pilot, repeat battle. 20 years of accumulated craftsmanship producing industry-best DRPG operability.
② Beginner Onboarding
"I thought DRPGs were punishing, but a complete novice like me could clear it" — a consistent design philosophy from Demon Gaze through Labyrinth of Yomi. Experience expanded the gates to the DRPG market.
③ Character Build Flexibility
Zero penalty for class changes, free stat respec. "I loved being able to try all kinds of builds."
④ A World Only They Own: Showa Dystopia
1979 Tokyo × underground labyrinths. No other DRPG on Earth has this combination.
⑤ Proven Horror ADV Track Record
Death Mark Steam 85%, NG 92%. Established as a J-Horror brand overseas.
⑥ The President's Closeness to Fans
Cat photos, cooking posts, "I'm bleeding from my eyes..." — the human side of development. The biggest weapon a small studio can wield: being a face, not a logo.
Weaknesses: What a Paid Consultant Would Say
This is not an attack. It is a visualization of "structures that make it harder for fans to spend money they're ready to spend."
① Thin Storytelling (Design)
"The Showa × isekai setting is interesting but underutilized." "Story is neither good nor bad." World-building is first-rate; narrative is second-rate.
② Monotonous Skills (Design)
"Higher classes make all lower skills useless." "Too formulaic." Build freedom is the selling point, but the optimal path is a straight line.
③ Pricing Failure (Marketing)
Lite version + DLC split → criticized as "doing the same thing as Ubisoft." The core complaint is not price but trust cost: "It looks like they cut one game into two halves."
④ Insufficient Portraits (Development)
Character creation freedom is the selling point, yet portrait options are lacking.
⑤ "No One Good at Business" (Management)
Direct quote from an external reviewer: "They're a team of craftsmen, but they don't seem to have anyone good at the business side."
⑥ Slow Platform Strategy
Late to Steam/PS5. Multi-platform speed is now a survival requirement.
Root Cause (GPT Structural Audit)
"Development capability exists, but product management is weak."
Management weakness (no product owner) → fragmented design decisions → resource imbalance → purchase-time distrust → fan complaints.
Experience's real challenge is not development capability. It is "the power to cut and package as a product."
§2.5 The Treasury — Assets Proven by Fan Voices
We identified challenges in §2. But looking only at challenges leads to misjudging what to protect and what to change. Here we make visible the "real treasures" Experience holds.
Treasure ①: The Pillar of the DRPG Market
No other company in Japan has remained fully specialized in DRPGs, independently, for 20 years. Not Atlas, not Nippon Ichi — those are general publishers where DRPGs are one item in a portfolio.
15 employees, ¥3M capital. Surviving 20 years at this scale proves three things:
- A loyal fan base exists that buys every release
- Development efficiency is extraordinarily high
- Brand trust is established — each new title automatically commands attention
Treasure ②: They Created the De Facto Standard for Modern DRPGs
High-speed combat, auto-movement to marked coordinates, optimized hack-and-slash UI — these are now "standard" in DRPGs. Experience pioneered and refined them through Generation XTH and Demon Gaze.
Without this "comfort infrastructure," DRPGs would have remained "slow, archaic masochist games" that could never acquire new players. The genre might have died. Other studios copying these features is proof that Experience wrote the rulebook for modern DRPGs.
"I wish every DRPG had combat this fast" — Amazon review
Treasure ③: A J-Horror Brand That Crosses the Language Barrier
A 15-person studio achieving Steam Very Positive (85-92%) with a text-heavy horror ADV is an extraordinary strategic asset. Text adventure is the genre where the language barrier is thickest. That it resonates with overseas J-Horror fans means Experience's "damp, uniquely Japanese terror" has reached a universal artistic standard.
"Spirit Hunter Death Mark is probably one of the best horror VN. Really creepy and scary..." — @RanarifSC (1,260 likes)
"I love the artwork used in Death Mark... the art is really good" — @opoonaforwii
"Spirit Hunter" is an internationally recognized passport for competing on the global Steam market.
Treasure ④: "Played It Dozens of Times" — The Depth of Fan Attachment
"Demon Gaze... I've replayed it so many times..." — @yuuyuuyuuyuu (101 likes)
"Stranger of Sword City on Vita, replayed it countless times... a masterpiece I want to play again and again" — @SP1CAT1E1C
"I love the specters in Death Mark so much... thank you for making such a wonderful game!" — @yamada_mujika (40 likes)
"Seeing the president's X posts, I could feel the love for their own games... I like games where the creators' hearts are in it" — @bunntyousama
Users aren't just buying games. They're cheering for Experience's survival. An asset that billions in advertising cannot buy.
Treasure ⑤: The Only Company in the World with Both
A world-class horror ADV IP (Death Mark / Spirit Hunter) AND 20 years of refined DRPG system engineering, both developed in-house — no other company on Earth holds both.
This is the foundation of this report's recommendation.
Three Things That Must Not Be Broken (GPT Audit)
| DNA to Protect | Why It Must Not Be Broken |
|---|---|
| Comfort | Lowered DRPG entry barriers through QoL. Break it and new players stop coming |
| Dense Atmosphere | Remembered not just for systems but for "air." Dilute it and differentiation vanishes |
| Beginner Friendliness | Ability to package a hardcore genre with a non-threatening entry point. Lose it and the brand can't reproduce |
§3 Market Environment: Wizardry Daphne Rewrote the Rules
Daphne's Success Dissected
| Metric | Value |
|---|---|
| Worldwide Downloads | 3 million (Mar 2026 official) |
| App Store Rating | 4.6/5.0 (72,000 reviews) |
| Estimated Monthly Revenue | ¥100M+ (iOS avg rank ~134) |
What changed the rules: abandoned "free mobile = easy," implemented punishing difficulty, permadeath fear, and severe resource management in a F2P model.
Won: Old Wiz fans, FromSoftware-style death game fans, efficiency-focused 20-30s mobile gamers
Didn't win: Waifu crowd, auto-battle casual crowd
DRPG Market Size (TAM/SAM/SOM)
| Segment | Estimated Users | Estimated Value |
|---|---|---|
| TAM (Global DRPG) | 5-8 million | ¥50-80B ($330-530M) |
| SAM (Japanese DRPG) | 1.5-2 million | ¥15-30B ($100-200M) |
| SOM (Experience obtainable) | 30K-100K units | ¥300-800M ($2-5.3M) |
Competitive SWOT
| Competitor | Strength | Weakness | Opportunity | Threat |
|---|---|---|---|---|
| NIS (Labyrinth of Refrain) | Brutal narrative | Slow dev cycle | "DRPGs that make you cry" | Self-destruction risk |
| Atlus (Etrian Odyssey) | Mapping joy | Dual-screen legacy | Switch 2 | Daphne stealing market share |
| Wizardry Daphne | 3M DL base | Inflation risk | Steam expansion | Daily fatigue |
| Steam Indies | Niche focus | Budget limits | Portable PC growth | Buried in sales |
2026 DRPG Trends
Demand for story-driven DRPGs is structural and permanent.
Pure hack-and-slash cannot beat live-service games (Daphne) that add infinite content. The only survival path for buy-to-play DRPGs is "a dense, complete narrative experience with an ending."
On Steam, "DRPG" alone gets buried. Only titles with powerful hooks — "Japanese," "Horror," "Yuri" — survive.
§4 Question: What Should the Next DRPG Be?
Converging all data:
- §2's greatest weakness: thin storytelling
- §2.5's greatest untapped asset: Death Mark's narrative power (Steam 85-92%)
- §3's market proof: Daphne proved story-driven DRPGs sell
- §3's competitive map: Daphne = dark fantasy, NIS = emotional, Etrian = mapping joy
- Steam trend: no powerful tag = buried
- 15-person team cannot enter the 3D arms race
The territory Daphne didn't take: "modern Japan," "Japanese horror," "spiritual/psychological terror."
There is only one answer.
§5 Answer: Death Mark × DRPG — A Blue Ocean Reachable with Internal Resources
Why This Fusion Now
Cause ①: Internal assets fill the weakness. DRPG's weakness (story) can be filled by Death Mark's strength. No external hiring needed. Just merge two internal lines.
Cause ②: The market demands this fusion. Enter the "story-driven DRPG" market that Daphne proved exists — from a completely different angle than dark fantasy.
Cause ③: Zero competitors. A pure "Japanese Horror ADV × DRPG" does not exist in the world market. Complete blue ocean.
The Fusion Vision
World: Death Mark's Japanese horror (curses, specters, urban legends) × Yomi series' Showa dystopia (1970s-80s Tokyo, underground labyrinths)
Structure: Alternating Horror ADV and DRPG exploration segments. Gather intel in ADV → use that intel to conquer the dungeon in DRPG.
"Too scared to go deeper. But the story won't advance unless you do." — Terror and curiosity coexisting.
Combat: Not simple brawling. Use intel from ADV segments to exploit specter weaknesses — puzzle-like elements. Inject Death Mark's "choose wrong and die" tension into DRPG combat.
Competitive Differentiation
| Competitor | Position | Death Mark × DRPG Differentiation |
|---|---|---|
| Wizardry Daphne | Medieval dark fantasy × physical death | Modern Japanese horror × spiritual/psychological terror |
| NIS (Refrain) | DRPGs that make you cry | DRPGs that make you terrified |
| Etrian Odyssey | The joy of mapping | The fear of mapping |
No head-on collision with Daphne. Instead, a devastating counter aimed at the new audience Daphne opened up: "You learned to love dungeons? Now try a haunted school in modern Japan."
Risks and Countermeasures (GPT Audit)
| Risk | Probability | Impact | Countermeasure |
|---|---|---|---|
| Audience mismatch | High | Critical | DRPG as core, horror as flavor through exploration design |
| CERO rating constraints | Med-High | Critical | Design for CERO D ceiling. Replace Z-level content |
| Resource split | High | Critical | Fix shared asset scope. Max 1.5 parallel lines |
| Reduced replayability | Medium | Medium | Branch via horror events/class synergy, not story forks |
| Overseas localization | Medium | Medium | Pre-build specter encyclopedia and design intent docs |
GPT's core insight: "Success means adding Death Mark's strengths TO a DRPG — not turning Death Mark INTO a DRPG."
§6 Appendix: Survival Conditions for the Next 5 Years
Transform from "a development studio" to "a product design company organized by IP."
Three minimum structural reforms:
- Clear product ownership — a PM/producer who oversees planning, design, and pricing
- Fixed pricing/DLC/complete edition policy — "main game always complete; DLC is additional value only" as company rule
- Per-title experiential value KPIs — pre-set targets for story density, build branches, portrait count
