≈ $10k–$76k after Steam's cut

from ~414 reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

2 of the 8 similar games are hits.

Best case: The Test at ≈ 499k–810k copies, ≈ $273k–$734k after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like
About half the games that made it here had over 151 reviews in their first month; the range was 75 to 1k.
The genre you'd be entering
These games
The similar games share Choose Your Own Adventure (6 of 8) and Multiple Endings (6 of 8).
The winners
Winners here lead with Choose Your Own Adventure + Simulation, priced around $2. The breakout hits carry Psychological Horror + Simulation + Story Rich; a typical game here doesn't.
When they shipped
Only 1 of the 8 similar games shipped in the last two years. That says more about which games were found than about the market.
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).
