Blue Star is a narrative game inspired by the setting of Galactic Human Civilization from The Three-Body Problem, combining elements of role-playing and strategy simulation. The game focuses on the emotional identity crisis of post-human civilization regarding Earth’s culture during interstellar migration. Through diverse gameplay mechanics, it invites players to experience the tension of cultural inheritance and the complexity of individual choices as a sanitation worker aboard the Blue Space spaceship.

　　The design adopts a cinematic performance system, enhancing narrative expression through cutscenes and multi-perspective switching. Fragmented interactive objects and texts are introduced to encourage players to actively explore the world view. Core sci-fi concepts from The Three-Body Problem, such as the Dark Forest Law, are deeply integrated into the gameplay to boost immersion and philosophical reflection.
