A typical game among these

≈ 51k–99k copies

≈ $354k–$604k after Steam's cut

from ~2k reviews

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

6 of the 8 similar games are hits.

Best case: Kerbal Space Program at ≈ 7.2M–11.7M copies, ≈ $79.0M–$212.3M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering
These games
The similar games share 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.
When they shipped
The similar games span 2011 to 2025, and 1 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).
