Online Co-Op games on Steam

Online Co-Op on Steam: 6,206 released games, 1,888 in the last 12 months, 5,602 announced and still unreleased. Of the 2,945 released between three years and 90 days ago, the median has 29 lifetime reviews. 33% of them never reached 10 reviews. Free to play: 14%. Online Co-Op is a Steam store tag, applied by the developer and refined by players; a game carries several tags at once, so niche counts overlap and do not add up to the size of the Steam catalogue.
