Underrated Sci-fi indie games you missed
These are underrated sci-fi indie games: titles with strong reviews but not yet the audience they deserve. indielist surfaces 21 sci-fi games that each hold at least 80% positive Steam reviews while staying under 5,000 total ratings : the sweet spot where a game has proven itself with real players but hasn't broken out yet. Together they hold 56,165 reviews at an average of 89% positive. They are ranked by review count, so the most-validated picks lead, and each links to a white-box sales estimate you can open and check rather than a black-box number. The most reviewed here is GNOSIA with 4,878 reviews. Review counts and ratings are from Steam; sales figures are modeled estimates, not official sales data.
