Sonic's Movie and Anime Success Is Funding Better Games, Says Producer Takashi Iizuka

Takashi Iizuka, general producer of the Sonic the Hedgehog series, says the franchise's multimedia expansion into movies and anime is feeding back into game development in tangible ways. Speaking at Tokyo Game Show 2026, Iizuka described how increased investment in the Sonic brand, driven by the success of films and upcoming Netflix content, has allowed SEGA to allocate more resources to games and maintain both quality and release consistency.

The Sonic series is celebrating its 35th anniversary this year. Since the original Sonic the Hedgehog launched for the Mega Drive in 1991, the franchise has grown to over 1.77 billion cumulative units sold as of January 2026. At the show, SEGA showcased playable demos for Sonic Racing: CrossWorlds and SONIC PICO PARK, along with a live performance marking the milestone.

Iizuka's primary focus remains game development, though his responsibilities have expanded significantly. "My main profession is still making games, so my primary focus remains on developing new Sonic games," he said. "I'm overseeing Sonic Racing: CrossWorlds, as well as SONIC PICO PARK. I'm also working on some new titles that I can't talk about yet." However, he acknowledged that time spent on multimedia projects has increased alongside the franchise's growth into films and an upcoming Netflix kids' anime series.

When asked whether the expanded workload outside games bothered him, Iizuka said the growth reflects a stronger brand. "Having more work outside of games means that the Sonic series has grown stronger as a brand, and that we have more opportunities to work with other people, so in that sense, it's a good thing," he explained. "But if I go through an entire day without doing any game development work at all, I do get a little depressed."

Iizuka's role in multimedia projects involves preserving Sonic's character rather than overseeing creative decisions. With movies produced by Paramount Pictures, he acts as a character guardian. "I mainly provide advice to preserve Sonic's character," he said. "For example, saying that Sonic wouldn't behave in a certain way, or that the character designs should be a certain way." Unlike a traditional licensing department with predefined guidelines, Iizuka works without a formal framework, serving as what he calls "a living guideline for the IP" when new projects lack existing reference material.

Iizuka identified the 2020 release of the first Sonic movie as a turning point for the franchise. "If I were to define one more major period, I'd say it was around the time the movies came out," he explained. "The first movie was released in 2020, and thanks to its success around the world, the Sonic franchise grew dramatically. We now have plans for up to a fourth movie, so in that sense, I feel that a new generation began in 2020, when the Sonic brand started to expand."

The franchise has maintained a consistent release cadence, with new Sonic content appearing annually for 35 years, though development timelines have shifted. "Over the past 35 years, the Sonic series has released something new every year in one form or another," Iizuka said. He noted that development cycles have lengthened from roughly two years to three or five years for some titles, making annual releases more challenging to coordinate.

Despite longer development periods, SEGA has managed to maintain release consistency through parallel development lines. "By having multiple titles in development simultaneously, we've been able to deliver games properly, both in terms of quality and release timing," Iizuka said. This structure wasn't possible under the franchise's previous organization. "Yes, that's certainly something we couldn't have done under the old structure. A major factor is that the Sonic brand has grown stronger, which has allowed us to invest more money into it."

The increased investment is visible in review scores. Recent Sonic games have shown more consistent critical reception compared to earlier titles that saw wider score variation. Iizuka attributed this improvement directly to resources. "The biggest factor is the resources we can allocate to them," he said. "When the Sonic brand was struggling, we simply had less money to invest in each title, so we had to make do with what we had. Now, however, expectations for the Sonic series have risen, and we have more resources to put into it."

With a larger development infrastructure, SEGA can now redeploy staff to support projects falling behind schedule. "Now that our development teams have grown considerably, if, for example, one title looks like it might not make its deadline, staff from elsewhere can come in to support the project, allowing us to maintain both quality and stay on schedule," Iizuka explained.

Maintaining consistency across the Sonic portfolio requires active oversight. As general producer, Iizuka manages all titles as a unified effort, with each project having its own director and producer. This structure allows design innovations developed in one game to be carried forward into others. "In the past, when the Sonic series had a different organizational structure, each project evolved independently," he said. "One title might evolve in a certain way, while another title wouldn't inherit that evolution and would go off in a completely different direction. Now, however, by managing game production as a whole, if one title develops a new move, for example, we can carry that move over into another title."
