Games like Polyball

The middle of these games

≈ 1.7M–1.8M copies

≈ $16.6M–$23.6M after Steam's cut

from ~41k reviews

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

6 of your 8 similar games are hits.

Best case: Assetto Corsa at ≈ 9.7M–15.8M copies, ≈ $53.4M–$143.6M 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 25 reviews in their first month; the spread ran 1 to 6k.
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 Simulation (8 of 8).
The winners
Winners here lead with Racing + Automobile Sim, priced around $20. The breakout hits carry VR + Realistic; a typical game here doesn't.
The era
The games you compared span 2014 to 2026, and 1 of your 8 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
