AI Unlocks Infinite RPG Conversations

Fabula Rasa, an experimental VR game from Brazilian studio Arvore, made its global debut at the XR Exhibition at SXSW 2026. The game leverages Large Language Models (LLMs) to power fully improvised conversations, allowing players to create unique characters and engage in dynamic, real-time dialogues with AI-driven characters. This innovative approach promises to bring true role-playing to life by enabling players to generate original stories and side quests on the fly.

The gameplay centers on player interaction, where dialogue choices significantly impact outcomes. In one instance, a player's humorous remark about three dogs in a trenchcoat led to a knight character advocating for a stay of execution. Arvore's founder, Ricardo Justus, described the experience as akin to improv theater, where both players and characters riff off each other. This design ensures high replayability, with endings and character interactions varying based on player actions.

While the art in Fabula Rasa is handcrafted, the studio is exploring AI as a storytelling medium, not a replacement for human developers. Arvore uses models like Claude for dialogue and ElevenLabs for audio, aiming for rich, back-and-forth worldplay. Despite potential controversy surrounding AI in gaming, Arvore emphasizes that AI powers game mechanics and narrative. The technology, though still in its early stages, showcases a future where AI significantly enhances immersion in AAA games, potentially revolutionizing the industry.
