≈ 302k–384k copies

≈ $295k–$1.6M after Steam's cut

from ~8k reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

Your picks lean toward this genre's biggest survivors; the typical figure reads from its ordinary successes.

Best case: SpeedRunners at ≈ 1.5M–2.5M copies, ≈ $6.4M–$17.1M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering
Your set
Your set clusters on Platformer (7 of 8) and 3D Platformer (4 of 8).
The winners
Winners here lead with Platformer, priced around $10. The breakout hits carry Fast-Paced; a typical game here doesn't.
The era
The games you compared span 2011 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).
