The middle of these games

≈ 1k–3k copies

≈ $5k–$9k after Steam's cut

from ~45 reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

2 of your 8 similar games are hits.

Best case: Neverending Nightmares at ≈ 170k–276k copies, ≈ $700k–$1.9M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 20 reviews in their first month; the spread ran 11 to 341.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Horror (7 of 8) and Psychological Horror (6 of 8).
The winners: Winners here lead with Psychological Horror + Horror, priced around $15. The breakout hits carry Singleplayer; a typical game here doesn't.
The era: The games you compared span 2014 to 2024, and 1 of your 8 shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
