≈ $3k–$23k after Steam's cut

from ~146 reviews

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

1 of the 8 similar games is a hit.

Best case: Milk inside a bag of milk inside a bag of milk at ≈ 853k–1.4M copies, ≈ $349k–$939k 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 57 reviews in their first month; the range was 20 to 163.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Abstract (6 of 8) and Experimental (6 of 8).
The winners: Winners here lead with Visual Novel + Psychological Horror, priced around $1. The breakout hits carry Horror + Psychological + Interactive Fiction; a typical game here doesn't.
When they shipped: The similar games span 2017 to 2025, and 3 of the 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
