Our take on Sci-fi builder

Rather than following a campaign or survival arc, the game removes story and endgame structure in favor of freeform station construction, character direction, and improvised social scenes. The main activity is creating situations, not completing a prescribed sequence of objectives.

What is Sci-fi builder?

Create and manage a space station in an open-ended science-fiction construction and colony simulation.

Rooms can be arranged freely, with furnishings, equipment, decorative objects, color schemes, illumination, and visual effects placed without grid restrictions. The cast includes humanoid figures, extraterrestrial beings, mechanical characters, creatures, and other non-player inhabitants. Clothing, temperaments, and conduct can be adjusted for each one. Characters can be operated directly or assigned computer-controlled routines, producing relationships and social encounters. Building tools include station components, interior items, terminals, gadgets, and apparel. The game has no campaign or final objective; its structure focuses on unrestricted construction, roleplaying, growing settlements, and unexpected interactions between inhabitants and objects.
