The One Piece Pirate Warriors series has officially sailed past 10 million copies sold worldwide, Bandai Namco and Omega Force announced this week. For a franchise that started back in 2012 on PlayStation 3, hitting this milestone proves that licensed anime games can achieve long-term success when developers actually put in the work. With four mainline entries spanning over a decade, the Pirate Warriors series has become one of the most successful anime-to-game adaptations in the musou genre.

Breaking Down the Numbers
The 10 million figure represents combined sales across all four Pirate Warriors titles released between 2012 and 2020. One Piece Pirate Warriors 4, which launched in March 2020, carries most of the weight with 4 million copies sold on its own as of February 2025. That single entry accounts for 40 percent of the entire franchise’s sales, demonstrating how the series has grown its audience over time rather than declining like many long-running franchises.
The original One Piece Pirate Warriors released exclusively for PlayStation 3 in 2012, followed by Pirate Warriors 2 in 2013 on PS3 and PlayStation Vita. Pirate Warriors 3 expanded to PlayStation 4, PC via Steam, and eventually Nintendo Switch in 2015. By the time Pirate Warriors 4 arrived, it launched simultaneously across PlayStation 4, Xbox One, Nintendo Switch, and PC, with next-gen versions for PlayStation 5 and Xbox Series X coming later.
Why Pirate Warriors Succeeded Where Others Failed
Licensed anime games have a terrible reputation, and for good reason. Most publishers treat them as quick cash grabs designed to exploit a popular series’ fanbase without investing in quality development. Games based on Naruto, Dragon Ball, Bleach, and countless other shonen properties have flooded the market with mediocre experiences that feel more like interactive advertisements than actual games worth playing.
One Piece Pirate Warriors avoided this trap by partnering with Omega Force, the Koei Tecmo studio responsible for Dynasty Warriors and the entire musou genre. Omega Force knows how to make satisfying hack-and-slash combat where players cut through hundreds of enemies with flashy combos and devastating special attacks. By applying that expertise to One Piece’s world and characters, they created games that feel good to play while staying faithful to the source material.
The Musou Formula Applied to Pirate Adventures
For anyone unfamiliar with musou games, the formula is straightforward. Players select a character and battle through massive armies of disposable enemies while completing objectives across large maps. The core appeal lies in the power fantasy of single-handedly destroying entire battalions with increasingly elaborate combos and super moves. Dynasty Warriors pioneered this genre decades ago, and Omega Force has refined it through dozens of entries and collaborations.
Pirate Warriors adapts this template to One Piece’s pirate setting. Players control Luffy and the Straw Hat crew along with allies and enemies from throughout the manga and anime. Each character has unique movesets based on their Devil Fruit powers or fighting styles. Luffy stretches his rubber limbs to pummel crowds, Zoro slashes through formations with his three-sword technique, and Sanji kicks his way through dozens of marines with blazing combos.
The games follow major story arcs from the One Piece narrative, letting players relive iconic moments while battling through Alabasta, Enies Lobby, Marineford, and more recently the Whole Cake Island and Wano Country arcs. Pirate Warriors 4 introduced a new Titan Mode mechanic where certain enemies grow to massive sizes, forcing players to adjust strategies and dodge more carefully while targeting weak points.
Pirate Warriors 4 Leads the Charge
The fourth entry represents the pinnacle of the series so far. Releasing in March 2020 across all major platforms gave it the widest possible audience from day one. The game featured destructible environments, improved aerial combat, form changes for characters like Luffy’s Gear Fourth transformations, and the most extensive roster in franchise history with over 40 playable characters at launch.
Bandai Namco supported Pirate Warriors 4 with substantial post-launch DLC. Three character packs added fan-favorite fighters including Kozuki Oden, Kin’emon, O-Kiku, Charlotte Smoothie, and Vinsmoke Reiju. The Land of Wano Pack brought the Wano Country arc into the game with new story content and characters. Additional DLC packs released through 2025 continued expanding the roster years after launch, showing genuine commitment to supporting the game long-term.
The Bigger Picture for Licensed Games
One Piece Pirate Warriors proves that anime adaptations can achieve commercial success and critical respect when developers treat the source material seriously. Instead of churning out cheap arena fighters or lazy action games, Omega Force built proper musou experiences that happen to star One Piece characters. The distinction matters because it shows publishers that investing in quality pays dividends.
Compare this approach to most licensed games that barely function, release broken, or feel like mobile games ported to consoles. When studios actually care about the franchises they’re adapting and have the technical expertise to execute their vision, fans respond positively. The 10 million sales milestone for Pirate Warriors demonstrates sustained interest across over a decade, not just a quick burst of hype-driven purchases followed by abandonment.
How It Compares to Other Musou Games
Within Omega Force’s catalog, 10 million sales for the Pirate Warriors series is impressive but not unprecedented. Dynasty Warriors, the flagship franchise that defined the genre, has sold over 21 million units as of early 2025, though that figure spans dozens of mainline entries, spin-offs, and remakes dating back to 2000. Dynasty Warriors Origins alone sold over 1 million copies shortly after its February 2025 launch.
Hyrule Warriors Age of Calamity set a record for the fastest-selling musou game with 3 million copies shipped in its first few days back in November 2020. However, Pirate Warriors maintains stronger long-term sales across multiple entries compared to one-off collaborations. Fire Emblem Warriors and other licensed musou projects haven’t matched Pirate Warriors’ consistent performance across sequels.
What Comes Next for the Series
With Pirate Warriors 4 still receiving DLC updates in 2025, five years after its initial release, Bandai Namco and Omega Force clearly see value in continuing to support the current entry rather than rushing out a fifth game. This approach makes sense given how much story content One Piece has produced since 2020. The manga and anime have progressed through significant arcs including the conclusion of Wano, Egghead Island, and beyond.
Eventually, Pirate Warriors 5 seems inevitable. The series has established a pattern of releasing new entries every few years with expanded rosters, updated story content, and refined gameplay mechanics. A fifth entry could launch on PlayStation 6 and next-generation Xbox hardware, taking full advantage of improved processing power to render even larger battles with more detailed character models and destructible environments.
The Legacy of Successful Anime Games
One Piece Pirate Warriors sits alongside franchises like Dragon Ball FighterZ, Persona 5, and NieR Automata as examples of anime-styled games achieving mainstream success through quality development. Dragon Ball FighterZ partnered with Arc System Works to create a fighting game that respected both the license and the genre. Persona 5 became a cultural phenomenon that transcended its niche JRPG roots. NieR Automata proved that weird, experimental games from eccentric creators can find massive audiences.
These success stories share common threads. Experienced developers who understand their genres, publishers willing to invest properly in development, and respect for the source material that goes beyond slapping familiar characters into generic game templates. When all those elements align, licensed games can compete with original IPs and build dedicated fanbases that support multiple sequels.

Conclusion
Reaching 10 million sales across 13 years proves that the One Piece Pirate Warriors franchise has staying power that most licensed anime games can only dream about. By partnering with Omega Force, a studio that actually knows how to make compelling musou games, Bandai Namco created a series that respects both the One Piece license and the players who buy these games. The result is four solid entries that let fans live out their power fantasies as Luffy, Zoro, Sanji, and the rest of the Straw Hat crew. Pirate Warriors 4’s continued support with DLC packs five years after launch shows that Bandai Namco recognizes the value of nurturing this franchise rather than abandoning it after the initial sales rush. With One Piece’s story still ongoing and new arcs constantly providing fresh content to adapt, the Pirate Warriors series has plenty of runway ahead. Whether Pirate Warriors 5 arrives on current hardware or waits for the next console generation, the foundation has been laid for continued success. For other anime franchises looking to break into gaming with quality adaptations, Pirate Warriors offers a blueprint worth studying. Find experienced developers who understand the genre you’re working in, give them time and resources to build something worthwhile, and support the game post-launch with meaningful content. Do that, and maybe your licensed game won’t become another cautionary tale about wasted potential. Instead, it might just celebrate a 10 million sales milestone of its own.
