Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

A typical game among these

≈ 29k–57k copies

≈ $149k–$396k after Steam's cut

from ~974 reviews

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

4 of the 8 similar games are hits.

Best case: Starbase at ≈ 168k–273k copies, ≈ $1.6M–$4.3M after Steam's cut. It is a breakout hit, far above a typical game.

The winners
Winners here lead with Open World + Building, priced around $35. The breakout hits carry Open World + Massively Multiplayer + Space Sim; a typical game here doesn't.
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).
