Games like RollerBaller

The middle of these games

≈ 352k–705k copies

≈ $2.3M–$5.6M after Steam's cut

from ~13k 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.

Best case: Forza Horizon 4 at ≈ 7.5M–12.2M copies. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 6k reviews in their first month; the spread ran 2k to 42k.

The genre you'd be entering

Your set: Your set clusters on Racing (8 of 8) and Driving (7 of 8).
The winners: Winners here lead with Racing + Open World, priced around $60. The breakout hits carry Realistic + Multiplayer + Adventure; a typical game here doesn't.
The era: 4 of your 8 similar games shipped in the last two years, so this niche is actively shipping.

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).
