Autonomous Player Characters

What if a game character could surprise even the person who built them?

We’re working on that. Using AI, we’re transforming non-playable characters into actors that listen, respond, move, and perform — no scripts, no decision trees, no multiple choice. Just real-time, every time, differently.

It sounds like the future of games. It might also be the future of how we train doctors, teach history, and close the gap between knowing something and actually being able to do it.

The Problem With the Script

Every character in every game you’ve ever played was written.

Word for word, line by line, before a player ever touched a controller. A writer sat down and mapped every possible exchange — every question, every response, every branch in the conversation — because that was the only way it worked. The character wasn’t alive. It was a very sophisticated book.

The result is the constraint you’ve seen a thousand times: multiple choice.

Pick one of four options. The writer knew which one you’d pick, planned for it, and guided you toward the right answer. It kept the story manageable. It also hollowed out the experience.

A medical student choosing from four diagnoses isn’t thinking like a doctor. They’re taking a test.

Characters vs. Actors

We call them Intelligent Actors — and the name is deliberate.

A character is written. An actor is given a role, a set of behaviors, an emotional register, and then turns it into something no one fully scripted. Think Will Ferrell on set. Half of what made the scene was never on the page.

That’s what we’re building. An AI-powered game character that can hold a real conversation, choose how to move through a space, decide what emotion to express, and respond to what a player actually says and does — not just what the writer anticipated. You give the actor guidelines. A personality. A purpose. Then you let them perform.

AI dialogue without action = a very articulate statue.

We got the conversation working first — AI-generated dialogue, voice input, real-time response. The Intelligent Actor could talk beautifully. But when we dropped it into a game engine, something broke. Ask it to open a door, point across the room, walk somewhere — it just stood there. Turns out knowing what to say and knowing what to do are two completely different problems.

So that’s where the research is now: building out the full performance.

Teaching the actor to walk, gesture, animate, and emote — autonomously, in context, in real time. Not because we told it exactly what to do, but because it understands the scene well enough to decide.

For most games, this is a compelling upgrade.

For educational games, it changes what’s possible at a fundamental level.

The multiple-choice model doesn’t just limit gameplay — it limits learning. When you hand a student four options, you’ve already done half their thinking for them. You’ve narrowed the world to a set of manageable answers, and the student works backwards from the choices instead of forwards from the problem.

Real learning happens in the wide-open space before the options appear.

Imagine a patient walking into a medical training simulation. They describe their symptoms. The student asks follow-up questions — not by selecting from a menu, but by speaking freely, the way a real doctor would. The patient responds. Not from a script. Not from a decision tree. Just responds. The student has to actually think. And the actor can meet them wherever they go.

This is active research.

Which means it’s a moving target, and we want it that way.

We’re documenting what used to be a limitation and isn’t anymore. Interviewing players and designers. Testing what happens when you take the script away. The work here isn’t about proving a number. It’s about proving a new way of building — and then handing that playbook to anyone who wants to build better.

We’re looking for people who want to work on it with us.

If you’re a researcher, developer, or educator who wants to explore what AI-driven characters could mean for your field, we want to hear from you. This one’s still being written. You can help write it.
