The niche at a glance

Underwater on Steam: 1,038 released games, 386 in the last 12 months, 544 announced and still unreleased. Median lifetime reviews: 10. 49% of them never reached 10 reviews. Free to play: 10%. Underwater 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.

48 pairings cleared 20 releases; 111 more never reached 5 and are not listed. Compared against 6.7% for games that carry any tags at all.

About these numbers

“Adjusted” is the share pulled towards the catalogue with the weight of twenty releases: the top of any ranked list is optimistic (out of a hundred pairings one will show 35 % on 23 releases by luck alone), and the adjustment is what stops a small lucky group from leading. The band next to the raw share is the 95 % interval. This list is the same for everyone today; the second opinion is the description-based one on Pitch comps.
