Why it matters
It expands gaslamp fantasy into cosmic territory, using spacefaring locomotives, imperial horror, literary exploration and gothic wit to build one of modern steampunk-adjacent gaming's strangest worlds.
Sunless Skies looks at Victorian imperial ambition and decides the obvious next step is locomotives in space, because apparently the heavens also needed timetables.
Developed by Failbetter Games and released in 2019, Sunless Skies takes the Fallen London universe into the High Wilderness, where locomotives travel through space and the British Empire has done what empires do when handed impossible geography: claimed far too much of it. The result is part exploration game, part literary RPG, part cosmic joke told by someone with excellent diction and worrying eyes.
The central image is irresistible: a locomotive sailing between stars. Steampunk already loves trains because they mean industry, timetables, class and expansion. Sunless Skies takes the train off the rails of Earth and sends it through celestial regions full of horror, bureaucracy, gods, monsters and beautifully phrased bad decisions.
Its gaslamp quality is stronger than its conventional steampunk machinery. The game is less about boilers and more about imperial imagination, occult geography, Victorian manners and the dreadful elasticity of empire. Yet the locomotives, stations, industrial extraction and period language keep it close to the field. It is steampunk's cosmic cousin, wearing a conductor's cap and carrying a very unsettling map.
The writing is the true engine. Failbetter's style is dense, witty, macabre and precise, turning every port into a little cabinet of horrors. Steampunk can become visually noisy while saying very little; Sunless Skies does the opposite. Its prose makes the world feel deep, dangerous and absurd before any machinery is described.
Its relationship to Space: 1889 is especially interesting. Both works send nineteenth-century assumptions into space, but they do so with different moral weather. Space: 1889 is scientific romance adventure. Sunless Skies is stranger, darker and more openly critical of imperial hunger. It knows that if empire reaches the stars, it will bring forms, guns and appalling confidence.
The game's survival and trading systems make the setting more than text. Fuel, supplies, crew terror, bargains and routes all matter. A locomotive in space is romantic until the hold is low and the next port has teeth. That practical pressure keeps the cosmic weirdness grounded in resource management, which is one of the genre's better habits.
For a modern canon, Sunless Skies is essential as an example of literary steampunk-adjacent game design. It proves that the genre can go vast without becoming empty. The sky is not the limit here. It is merely the platform.
It also gives empire a suitably absurd afterlife. The British project does not become nobler because it has left Earth. It becomes stranger, more brittle and more grotesque, with bureaucracy and hunger trailing behind the locomotive. That satirical pressure keeps the game's beauty from turning soft.
The ports and officers, meanwhile, keep the experience human. Beneath the cosmic scale are crew members with fears, stories and inconvenient needs. The locomotive may be the great image, but the journey is carried by people, supplies and the uneasy knowledge that the next stop might be worse than the last.
Is it really steampunk?
Adjacent, but very strongly. Sunless Skies is gaslamp cosmic fantasy with locomotives, imperial industry, Victorian language and gothic machinery rather than standard steam-era alternate history.
It suits players who like their steampunk literate, star-haunted and slightly too well dressed for the abyss.
