A typical game among these

≈ 627–751k copies

≈ $2k–$225k after Steam's cut

from ~250 reviews

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

3 of the 8 similar games are hits.

Best case: Supermarket Together at ≈ 2.5M–4.0M copies.

What their first month looked like

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
