The middle of these games

≈ 326–2k copies

≈ $182–$8k after Steam's cut

from ~35 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: Gas Guzzlers Extreme at ≈ 261k–424k copies, ≈ $1.8M–$4.8M 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 17 reviews in their first month; the spread ran 2 to 55.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Zombies (7 of 8) and Combat Racing (5 of 8).
The winners: Winners here lead with Combat Racing + Vehicular Combat, priced around $25. The breakout hits carry Multiplayer + Sports + Racing; a typical game here doesn't.
The era: The games you compared span 2013 to 2025, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
