≈ 204–862 copies

≈ $251–$879 after Steam's cut

from ~11 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: Portal 2 at ≈ 29.5M–48.0M copies, ≈ $81.1M–$218.1M 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 4 reviews in their first month; the range was 1 to 12.
Games with under about 100 reviews in month one almost never recover.
The genre you'd be entering
These games
The similar games share Platformer (5 of 8) and Physics (4 of 8).
The winners
Winners here lead with Platformer, priced around $9. The breakout hits carry Funny + Platformer + First-Person; a typical game here doesn't.
When they shipped
The similar games span 2011 to 2025, and 2 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
