≈ 51k–98k copies

≈ $354k–$595k after Steam's cut

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

6 of your 8 similar games are hits.

Best case: Kerbal Space Program at ≈ 7.1M–11.6M copies, ≈ $78.6M–$211.3M 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 1k reviews in their first month; the spread ran 315 to 1k.
The genre you'd be entering
Your set
Your set clusters on Space (7 of 8) and Simulation (6 of 8).
The winners
Winners here lead with Space + Simulation, priced around $35. The breakout hits carry Physics + Sandbox + Science; a typical game here doesn't.
The era
The games you compared span 2011 to 2025, and 1 of your 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).
