≈ $1k–$68k after Steam's cut

from ~63 reviews

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

3 of your 8 similar games are hits.

Best case: Phasmophobia at ≈ 20.8M–33.8M copies, ≈ $114.2M–$307.1M 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 32 reviews in their first month; the spread ran 9 to 40k.
Under about 100 in month one, almost nothing recovers.
The genre you'd be entering
Your set
Your set clusters on Horror (8 of 8) and Psychedelic (7 of 8).
The winners
Winners here lead with Horror + Psychological Horror, priced around $20. The breakout hits carry Online Co-Op + Multiplayer + Psychological Horror; a typical game here doesn't.
The era
Only 2 of your 8 similar games shipped in the last two years. That says more about your picks than about the market, so add newer similar games to read the timing.
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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
