Underrated Online Co-Op indie games you missed
These are underrated online co-op indie games: titles with strong reviews but not yet the audience they deserve. indielist surfaces 19 online co-op 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 39,871 reviews at an average of 87% 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.
