Best sci-fi games on Steam
The best-reviewed science fiction games on Steam. Ranked by review score weighted by how many reviews stand behind it, not by the raw percentage — a game with 40,000 reviews at 92% places above one with 210 at 96%, because a small crowd of enthusiasts is not the same thing as a verdict.

The badge on each cover is the share of Steam reviews that are positive. Only games with at least 200reviews are eligible, and the order weights that share by how many reviews back it, so a large review count beats a slightly higher percentage from a small one. Prices are today’s US Steam prices and update hourly; player counts are live from Coilr’s own tracking.
