Abstract
Recent advancements in AI, driven by Large Language Models (LLMs) and diffusion -based generative models have significantly enhanced the field. These models produce creative outputs comparable to human creations, expanding possibilities for automated creativity. While generative AI is used in game development, research on integrating automatic dialogue and environment generation as core game elements is limited. This study constructs a game system with dynamic scene transitions in response to user input. Specifically, we develop an adventure game that defines scene transitions and generates natural sequences in user-character dialogues for personalized dialog to create comfortable user experience, offering a co-living experience with AI agents reflecting user preferences.
