Critical Role’s founders built an empire on friendship, dice rolls and shared storytelling. Now, as the fourth season of their flagship animated series lands to widespread acclaim, they stand firm against a technology many peers have embraced.
The Legend of Vox Machina returned to Prime Video on June 3. It earned a perfect 100% on Rotten Tomatoes, matching the scores of its previous three seasons. Forbes reported the achievement marks the fourth consecutive perfect critic score for the show. Yet the numbers tell only part of the story. Behind the polished frames lies a deliberate choice.
No AI. Not for writing. Not for art. Not for music. The eight cofounders said it plainly in recent interviews. They won’t use the tools that promise faster production or lower costs. Art isn’t supposed to be easy. That’s what makes it worthwhile.
Business Insider sat down with the team ahead of the season’s launch. Matt Mercer, chief creative officer and Dungeon Master, cut to the heart of their resistance. “A computer cannot be passionate. And the whole reason that Critical Role is here isn’t just because of great stories or because of a magnificent fantasy realm. Ultimately, it’s because of us being friends caring about each other and being so invested in this story together.”
Passion. Investment. Human connection. These ideas surface again and again. The series began as a private Dungeons & Dragons game among friends in 2015. It exploded into a cultural force after they streamed it. A record $11.3 million Kickstarter in 2019 funded the first animated specials. Amazon came aboard for the full series. Three seasons later, the show has expanded into books, a tabletop game called Daggerheart, live arena tours and a second animated series based on their second campaign.
Season 4 picks up a year after the Chroma Conclave. The party has scattered. They chase love, family and purpose. Old threats resurface. New allies appear, including Taryon Darrington voiced by Wayne Brady. The tone darkens in places. Levity arrives through familiar banter and fresh characters. Creators spoke to Animation Magazine about the challenges of adapting a decade-long campaign. They plant seeds early. They cherry-pick moments from the larger Exandria world that deliver visual punch. Production involves Titmouse in the U.S. and Production Reve in Seoul. The process takes years. The cofounders accept that timeline.
Travis Willingham serves as CEO and voices Grog. He explained their view on craft. “We’ve been the incredible recipients of watching those people at the highest level do their work. To me, that’s something that can never be replaced by a machine or a program.” The team employs writers and artists from multiple countries. The founders stay deeply involved. They contribute to character designs. They write episodes. Liam O’Brien and Marisha Ray co-wrote a heist episode this season titled “De Rolo’s Eleven.”
O’Brien addressed the appeal of flawed characters. “We crave other people telling stories. That’s what we’ve done from the very beginning and AI is promising us perfection in a facsimile. And I think what we love about the characters in our story is they are flawed and have so many wrinkles and problems. And I don’t know that that promise of perfection even appeals.” Short sentences. Clear rejection. The imperfections matter.
Sam Riegel, who voices Scanlan and serves as an executive producer, doubled down in a separate conversation. He and music producer Peter Habib created original songs for both Vox Machina and the new Mighty Nein series. Their process starts with scripts. They discuss themes. They iterate on lyrics and instrumentation long before animatics lock. They record vocals with Broadway-caliber talent like Anika Noni Rose and Auli’i Cravalho. Habib built custom sounds for one track, attaching a plastic blow tube to a tambourine for a unique timbre.
When asked about artificial intelligence, Habib noted some peers experiment with it as an idea generator. Riegel did not mince words. ComicsBeat captured the exchange. “I think our opinion is that it’s basically garbage,” Riegel said. He laughed, then continued. “There are people and artists who use it like Peter is talking about. But we’re not one of those. It’s so funny because AI was first pitched to the world as a helpful tool that would free you up to do the things that you never have time for and the things human beings want to do like appreciate life and art and be creative. But now it seems like the new pitch from these AI companies is, ‘AI can do that too. It can create and make poetry and music.’ But that’s what makes us human beings and why would we give that away?”
He finished the thought. “Art isn’t supposed to be easy. That’s what makes it worthwhile. No AI was used in any of this, and we don’t have any intention of using AI in the future.”
Polygon highlighted the comments days later. The piece noted the growing number of entertainers warming to AI tools. Critical Role chooses the opposite path. Their stance applies across writing, visual production and music. It covers The Legend of Vox Machina through its fifth and final season, already renewed. It extends to Mighty Nein and any future projects.
Industry watchers take notice. Animation budgets remain high. Timelines stretch. Studios hunt efficiencies. Some have integrated generative tools for concept art, background plates or even script drafts. Critical Role’s founders watched those developments. They weighed the trade-offs. Human collaboration won.
The cast voices their original characters. Laura Bailey as Vex’ahlia. Taliesin Jaffe as Percy. Ashley Johnson as Pike. Marisha Ray as Keyleth. Liam O’Brien as Vax’ildan. Sam Riegel. Travis Willingham. Matthew Mercer. Their performances carry decades of table talk. That history shows in the animation. Facial expressions, timing, emotional beats. Machines struggle to replicate lived chemistry.
Yet the decision carries risks. Faster competitors could flood the market with lower-cost fantasy animation. Audiences conditioned to weekly releases might grow impatient with gaps between seasons. Critical Role accepts those tensions. They bet fans value the care.
Early reactions to season 4 suggest the wager pays off. Critics praise the character work, the escalation toward larger threats and the balance of humor and darkness. The show sets up the Vecna arc that defined their first campaign. It teases connections to future stories. But it refuses shortcuts.
Production Reve and Titmouse deliver consistent quality. Preproduction focuses on designs and effects. The founders review animatics. They adjust. They argue. They refine. That friction produces the final product. Remove the human debate and something essential disappears.
Riegel addressed the song for Mighty Nein that became “Who Will You Be?” Themes of reinvention. A burlesque number set in a fantasy court. Not standard. They swapped instruments. They iterated. They recorded. The process stretched months. No algorithm supplied the melody or the emotional core.
The same principle guides the broader operation. Critical Role expanded into a full media company. They publish their own game. They tour arenas. They maintain the live-streamed campaigns that started everything. Through it all, the eight friends remain at the center.
Mercer described the origin. A game in his and Marisha Ray’s living room. Thousands of hours streamed. A fanbase that funded their ambitions. The animation wing grew from that foundation. It never drifted far from the original spirit.
So the fourth season arrives without AI assistance. The fifth will follow the same rule. The cast will voice their roles. Artists will draw each frame. Writers will shape the scripts. Musicians will compose the songs. The wait between seasons may frustrate some. The final product carries the weight of deliberate effort.
Industry insiders understand the subtext. In a moment when many chase efficiency, one prominent voice says the cost is too high. Passion cannot be synthesized. Flawed characters lose their wrinkles under algorithmic perfection. Human investment cannot be programmed.
The dice keep rolling. The story continues. And Critical Role has made clear how they intend to tell it.
