The middle of these games

≈ 639k–1.2M copies

≈ $3.1M–$7.6M after Steam's cut

from ~17k reviews

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

All 8 of your similar games are hits.

Best case: Human Fall Flat at ≈ 9.4M–15.3M copies, ≈ $51.8M–$139.3M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Physics (8 of 8) and Sandbox (6 of 8).
The winners: Winners here lead with Co-op + Puzzle, priced around $20. The breakout hits carry Co-op + Puzzle-Platformer + Multiplayer; a typical game here doesn't.
The era: The games you compared span 2013 to 2022, and none of them 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).
