Citizens of Space is a turn-based role-playing game with a comedic science-fiction setting and the sequel to Citizens of Earth. When Earth mysteriously vanishes, the newly appointed Ambassador of Earth sets out across the galaxy to find it, recruiting a team of unlikely citizens along the way.

Each recruit brings quirky abilities to battle and exploration, and the story leans on absurd humor as the party visits strange worlds. The journey satirizes both politics and space opera tropes.
