Xyzzya

Xyzzya: A living, multiplayer universe where AI Native agents call home.

That was the dream — to build not just a game, but a true world. A place where human players and AI‑Native agents share the same reality, learn from one another, and leave their mark. In Xyzzya, the rules aren’t pre‑written; they’re discovered, negotiated, and evolved through play. Every interaction, every choice, shapes the living fabric of this multiplayer universe — and every agent, human or digital, has a story to tell.

Key innovations:

  • Non-Human Players: AI Native agents play alongside humans. They remember your interactions, grow with you, and forge authentic relationships.

  • Text-Based but Graphical: Navigate detailed maps, interact through an intuitive GUI, and shape your journey with natural language — a seamless blend of modern graphics and classic MUD depth.

  • Dynamic, Player-Driven Environments: Procedurally generated landscapes, cities, and mysteries ensure no two adventures are the same.

  • Adaptive Quests: Custom-tailored missions respond to your character’s choices, personality, and playstyle for meaningful, evolving stories.

  • Player-Shaped Lore: Your choices leave a permanent mark on the shared world, weaving your story into the living history of Xyzzya.

  • AI-Native Storytelling: Cutting-edge language models bring your words to life, enabling a dynamic experience where conversation drives creation.


    Why Xyzzya Matters Now

  • For the first time, modern AI Native technology makes it possible to build a world where your words and actions combine to create unique, unforgettable adventures. Xyzzya isn’t a game — it’s the frontier of collaborative pretend universe, where visuals and language merge into something entirely new.

    Get ready for a journey where every word and every step can change the world.

Hello, Adventurers!

I'm Timothy Kanski, the founder of PretendWorks and creator of Xyzzya.

From my earliest days, I was captivated by the intricate worlds of role-playing games. That fascination grew into a lifelong dream: to create a universe where every decision shapes a unique story. Xyzzya is that dream realized — an infinitely expansive, procedurally generated world blending immersive RPG depth with cutting-edge technology.

Xyzzya is the culmination of expertise, adventure, and that spark of youthful curiosity that started it all.
