Games like Space Simulation Toolkit

A typical game among these

≈ 771k–6.2M copies

≈ $8.9M–$65.5M after Steam's cut

from ~51k reviews

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

All 8 of the similar games are hits.

Best case: BeamNG.drive at ≈ 20.5M–33.4M copies, ≈ $141.2M–$379.6M after Steam's cut.

The genre you'd be entering

These games: The similar games share Physics (8 of 8) and Sandbox (8 of 8).
The winners: Winners here lead with Simulation + Driving, priced around $25.
When they shipped: The similar games span 2014 to 2026, 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
