A typical game among these

≈ 234k–330k copies

≈ $271k–$721k after Steam's cut

from ~7k 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: Cookie Clicker at ≈ 2.3M–3.8M copies, ≈ $3.2M–$8.5M 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 Clicker (6 of 8) and Idler (5 of 8).
The winners: Winners here lead with Clicker + Idler, priced around $5. The breakout hits carry Horror + Economy + Indie; a typical game here doesn't.

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