What matters: Sci-fi open-world games

Sci-fi open worlds come in several flavors, and the first thing to decide is what kind of freedom you want. Some games hand you a whole galaxy and let you set your own goals, while others place you in one dense, story-driven city or on a single hostile planet. The tags on this list show the split clearly: exploration and survival on one side, RPG and story on the other.

If you want to roam without a fixed path, No Man's Sky offers survival, exploration and co-op across a huge number of planets, and it is available on PC, PlayStation, Xbox and Nintendo Switch. Elite: Dangerous is tagged Difficult and aimed at players who like a more demanding space experience. For a calmer trip, SpaceEngine is tagged Relaxing and Realistic and is more about looking around than surviving. If you prefer a guided narrative, Cyberpunk 2077 combines an open city with an RPG structure, a first-person view and a story-rich setup.

Also check the pace and the platform. Subnautica is a survival game with Horror and Atmospheric tags, so it suits you if you like tension while you explore. Star Citizen and SpaceEngine are PC only, while Outer Wilds, a mystery-and-puzzle game about exploring space, runs on all four platforms listed. Fallout 4 is the pick here if you want a post-apocalyptic RPG with shooting.

Frequently asked questions
