At the Baidu Cloud Intelligence Conference, RPGGO showcased the generative AI game engine - Zagii Engine, which can create multiplayer dynamic role-playing murder mystery games within 20 minutes. This engine accelerates the AI game production process and enhances UGC creation capabilities and content quality. RPGGO plans to open-source the engine to help creators simplify the development process and achieve maximum creative output. AI NPCs adapt to the game world settings, interact with players in a survival-style manner, and influence the development of the game story. RPGGO demonstrated a pixel-art murder mystery game with real-time AI NPC dialogue decryption, showcasing the UGC application scenario from text to game.
