This talk discussed how NautilIA was integrated into a French as a Foreign Language course and illustrated how learners interacted with the game across multiple classroom sessions. The talk presented preliminary findings from an ongoing mixed-methods study, drawing on learner performance data, gameplay telemetry, and participants’ perceptions. These findings will highlight emerging patterns related to oral proficiency—including fluency, intelligibility, and comprehensibility—as well as learner engagement and interaction with the AI-mediated environment. The talk concluded by considering the pedagogical affordances and current technical and instructional limitations of generative-AI roleplay games for language learning, with particular attention to how emerging AI technologies can be leveraged to create more interactive and personalized language-learning experiences.
