The Future of Interactive Audio
Five ideas from a conversation with Robyn Pacetti, founder of Protagonists!
Robyn Pacetti is the founder and CEO of Protagonists! Over the past 25 years, she's helped build large-scale, community-driven games at Amazon, Ubisoft, and Wooga. Her focus has always been creating worlds that players return to again and again. Today, she's applying those lessons to interactive audio.

Community-created worlds
Interactive audiobooks have been "the next big thing" for years.
The tech exists. Millions listen to fiction on Audible. Episode, Choices and other interactive fiction platforms engage large audiences. But interactive audio is still a niche.
Rather than adapting books into interactive experiences, her team is building persistent imaginary worlds—shared universes that remember player choices and evolve over time.
The idea grew out of Robyn's love of long-running audiobook series like Expeditionary Force. After finishing a series she loved, she found herself asking a simple question:
"Why couldn't I participate in those worlds instead of only consuming them?"
That question became the foundation for Protagonists!.
Our conversation ranged from narrative design and worldbuilding to AI and community creation. Five ideas stood out.
Every Medium Has Its Own Grammar.
One of Robyn's core beliefs is that interactive audio shouldn't try to imitate books.
“Our approach is different. We're focused on player agency, persistence, and consequence. Writing for audio also requires a completely different balance.”
That last point is really important. When you read a book, you control your pace. You can reread sections you find confusing, or you linger on a beautiful piece of prose. Listening to audio, on the other hand, is about flow and immersion.
Interactive audio adds another layer of complexity because listeners are making decisions while absorbing information. Writers have to carefully balance exposition, action, and player agency while managing what Robyn calls the listener's cognitive load.
For Protagonists!, that has meant reducing descriptive passages, increasing environmental storytelling, and designing interactions that feel natural without overwhelming the listener.
The Future is in Persistent Worlds.
One of Robyn’s biggest realizations was that they weren’t building an interactive audiobook.
“We're building what we call persistent imaginary worlds using "narrative bricks." The challenge becomes designing modular storytelling where players can revisit locations, undertake quests, and experience a world that remembers them.”
This is much closer to systemic game design than traditional writing.
One of the biggest challenges in interactive fiction is scale. Every meaningful choice creates more dialogue, more continuity problems, more testing, and more content to produce. Branching narratives quickly become a mess to maintain.
A systems approach changes that equation. Instead of writing every possible story path, designers build rules that allow stories to emerge through interaction. That's the secret behind open-world games. It's far less common in audio storytelling, which makes Protagonists! particularly interesting. In many ways, the platform feels less like another interactive fiction app and more like an audio-first sandbox.
Consequences Matter More Than Choices.
One of the most interesting ideas from our conversation was about the idea of permanence.
“We want players to feel that their decisions matter. That's why we don't want people rewinding and undoing choices. If every decision can simply be reversed, it destroys the illusion that you're truly living inside another world.”
On the surface, that can sound punishing, but it’s actually standard for many choice-based games. While the idea of rewinding choices and trying different paths sounds fun in theory; in practice it can break immersion. A bad choice outcome for a player gives weight and meaning to the experience and drives home the idea that every choice matters.
This is where persistent worlds become especially compelling. Instead of treating failure as something players immediately undo, the world itself changes in response to the player's actions. Building technology capable of supporting that level of responsiveness is a significant challenge, but it's also what makes the vision feel genuinely different from traditional branching narratives.
AI Should Remove the Work, Not the Creativity.
Robyn is building her product at the growing intersection of AI and storytelling. But unlike those who view AI as a silver bullet tool, Robyn has a nuanced perspective.
“Creative leadership is about making decisions, defining boundaries, and knowing when to say no. AI is actually very poor at that. It generates possibilities but lacks vision.”
A.I. without human taste and judgement can produce mediocrity; a safe but often bland average of what has worked in the past. You need the weirdness, roughness and unpredictability of human storytelling to create richness and emotion. Creatives directing A.I. has potential to create responsive storytelling systems that wouldn’t be possible manually.
But where AI can truly excel, according to Robyn, is as production infrastructure.
“It can help maintain consistency across enormous bodies of writing, update world bibles, analyze narrative continuity, eliminate repetitive work, and support quality control.
Though A.I gives creators more control, Robyn thinks it also raises important questions about authorship, ownership, and creative responsibility. Maintaining human creative judgement will always be the key to quality. Even if studios use AI to scale production on branching narrative, actual writers and narrative designers with taste and skill will be critical to deliver on cohesiveness, emotionality and ingenuity. This is where community creation comes in.
The Long-Term Opportunity Is Community Creation.
Although Protagonists! is beginning with its own original universe, Robyn's long-term vision extends far beyond a single story world.
"We'd love creators to build their own experiences inside shared worlds."
The idea is that creators could build new regions, quests, and stories while working within a common narrative framework. Players would move seamlessly between those experiences without breaking immersion.
In many ways, the vision resembles platforms like Roblox more than traditional publishing. The goal is to build an ecosystem where other creators can tell stories inside the same persistent world.
Instead of isolated fan fiction or disconnected experiences, creators contribute to a living universe that continues to evolve over time. It's an ambitious vision that blends game modding, worldbuilding, and collaborative storytelling into something that doesn't yet fit neatly into an existing category.
Final Thought.
"Creative leadership is about making decisions, defining boundaries, and knowing when to say no."
Whether Robyn was talking about audio design, AI, or persistent worlds, the common thread was the same: great storytelling isn't about generating infinite possibilities, but making deliberate creative choices that gives a world its identity.
