A typical game among these

≈ 1.3M–3.2M copies

≈ $9.5M after Steam's cut

from ~51k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

Best case: Rocket League® at ≈ 28.3M–46.0M copies. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 5k reviews in their first month; the range was 55 to 21k.

The genre you'd be entering

These games: The similar games share Sports (6 of 8) and Football (Soccer) (4 of 8).
The winners: Winners here lead with Football (Soccer) + Competitive. The breakout hits carry Racing + Online Co-Op + Football (American); a typical game here doesn't.
When they shipped: The similar games span 2015 to 2022, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
