Why Kamen Rider’s New Mobile Games Keep Failing: A 15-Year Fan Analysis
Kamen Rider’s latest mobile game, Defense Warriors, has drawn widespread criticism for poor graphics, uninspired gameplay, and lazy design—a pattern that has plagued the franchise’s social games for years. After playing over 50 Rider-related games since 2015, one long-time fan breaks down the structural industry problems behind the franchise’s consistent decline in mobile gaming quality.
What Happened
Kamen Rider Defense Warriors, a tower defense mobile game, has been widely panned by fans for its poor production quality. The game features identical character artwork across different rarity levels (with only effects differing), static enemy animations, missing special attack sequences, and a generic story that fails to leverage the franchise’s rich character roster. This marks another disappointing entry in Bandai Namco’s mobile gaming lineup for the long-running tokusatsu franchise.
Why It Matters
Kamen Rider is a 50-year-old franchise with a dedicated global fanbase. Mobile games represent a critical revenue stream and marketing tool for major intellectual properties. When flagship franchises consistently release low-quality titles, it signals broader industry problems: the assumption that strong IP can sustain poor products, misallocation of development budgets, and a fundamental lack of respect for fan expectations. This pattern damages both player trust and the franchise’s long-term commercial viability.
Background
The author has been playing Kamen Rider games since 2015, experiencing the franchise’s mobile gaming evolution firsthand. Over nine years, they’ve played more than 50 Rider-related titles, including notable entries like City Wars (2017–2019), which ran for over three years with original voice acting and dedicated 3D models, and Doka Men (2021–2022), which featured a reported 200 million yen marketing budget but shut down after just 18 months. Defense Warriors represents a significant step backward compared to these predecessors, despite the lessons learned from previous failures.
Key Points
- Graphics and Animation Issues: Star 1 and Star 5 character illustrations are identical except for effects; enemy characters stand motionless; special attack animations are absent entirely
- Gameplay Design Problems: Tower defense is a poor fit for Kamen Rider’s action-oriented IP; the summoning system relegates iconic heroes to tools rather than protagonists
- Narrative Weakness: Original story lacks effort and depth; character introductions reduce to stat explanations rather than meaningful interactions
- Industry Complacency: Strong IP franchises often receive minimal effort because they generate revenue regardless of quality—a self-defeating cycle
- Comparison to Predecessors: City Wars and Doka Men, despite their flaws, demonstrated genuine effort and respect for the franchise that Defense Warriors completely lacks
- Projected Lifespan: The game appears designed to maximize initial monetization while minimizing ongoing development costs, suggesting a planned shutdown within 12 months
Timeline
- 2015: Author begins playing Kamen Rider mobile games; smartphone gaming market reaches maturity
- 2017: Battle Rush releases with high-quality action gameplay and character animations
- 2017–2019: City Wars operates successfully, featuring original voice acting and dedicated 3D models across three years
- 2018: Dragon Ball Legends demonstrates how proper rarity differentiation should work with distinct artwork and animations
- 2020: Summon Ride launches with awkward original character summoning mechanics
- 2021–2022: Doka Men runs for 18 months despite 200 million yen investment, then shuts down
- 2024: Defense Warriors releases with quality standards below 2010s-era browser games
Perspectives
The Fan Perspective: Players consistently express frustration that Defense Warriors represents a regression from even decade-old standards. Social media commentary repeatedly references “G123-level quality,” referring to outdated DMM browser games from the early 2010s. Fans note that City Wars, despite its imperfections, conveyed genuine effort and respect for the franchise, while Defense Warriors feels like a cynical cash grab.
The Industry Structure: The author’s analysis reveals a systemic problem: franchises with strong IP recognition face reduced pressure to maintain quality. Gundam mobile games, by contrast, have improved significantly since 2020 because the franchise maintains multiple revenue streams (films, anime, model kits). Kamen Rider, with declining new anime production, should theoretically prioritize mobile gaming—yet the opposite has occurred. This contradiction suggests budget reallocation away from mobile development.
The Business Model: Defense Warriors appears designed as a “front-loaded monetization” title: maximize initial spending through launch hype, then minimize operational costs (server maintenance, character development, marketing) to achieve quick profitability before inevitable shutdown. This contrasts sharply with City Wars’ approach of sustained, quality-focused operation.
Insights
The decline of Kamen Rider mobile games reflects three interconnected failures: (1) IP Undervaluation—the assumption that established franchises can sustain poor products; (2) Budget Misallocation—reduced investment in mobile development despite declining anime production; and (3) Talent Drain—the absence of passionate, franchise-literate developers who understand what makes Kamen Rider compelling.
Notably, City Wars and Doka Men succeeded not because they were perfect games, but because they demonstrated visible effort and respect for the source material. Players can distinguish between technical limitations and deliberate negligence. Defense Warriors fails this fundamental test.
The broader implication extends beyond Kamen Rider: major franchises that treat mobile gaming as a secondary revenue stream rather than a core experience risk eroding fan goodwill. The author’s recommendation is direct—Bandai Namco should either commit to quality mobile development with passionate creators, or suspend social game development entirely to focus on higher-quality media adaptations and physical products. The current approach satisfies neither players nor long-term business interests.
For fans, the practical advice is equally clear: avoid spending on new Kamen Rider mobile titles until the franchise demonstrates renewed commitment to quality. The franchise’s 50-year legacy deserves better than cynical monetization schemes.
