The middle of these games

≈ 6k–15k copies

≈ $9k–$27k after Steam's cut

from ~240 reviews

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

1 of your 8 similar games is a hit.

Best case: Race The Sun at ≈ 401k–652k copies, ≈ $1.1M–$3.0M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 44 reviews in their first month; the spread ran 16 to 384.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Racing (8 of 8) and Runner (5 of 8).
The winners: Winners here lead with Procedural Generation + Runner, priced around $10. The breakout hits carry Perma Death + Difficult + Tutorial; a typical game here doesn't.
The era: The games you compared span 2013 to 2021, 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 31 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).
