A typical game among these

≈ 630k–918k copies

≈ $7.3M–$10.6M after Steam's cut

from ~20k 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: 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.

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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
