A typical game among these

≈ 102k–160k copies

≈ $924k–$1.2M after Steam's cut

from ~3k reviews

7 of the 8 similar games are hits.

Best case: Yooka-Laylee at ≈ 186k–302k copies, ≈ $1.0M–$2.7M 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 Platformer (8 of 8) and Female Protagonist (3 of 8).
The winners: Winners here lead with Platformer, priced around $17. The breakout hits carry 3D Platformer + Collectathon + Kickstarter; a typical game here doesn't.
When they shipped: The similar games span 2012 to 2019, and none of them 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 36 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
