≈ $304k–$520k after Steam's cut

from ~2k reviews

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

7 of your 8 similar games are hits.

Best case: Automation - The Car Company Tycoon Game at ≈ 873k–1.4M copies, ≈ $7.2M–$19.4M 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 478 reviews in their first month; the spread ran 271 to 2k.
The genre you'd be entering
Your set
Your set clusters on Sandbox (6 of 8) and Simulation (6 of 8).
The winners
Winners here lead with Simulation, priced around $30. The breakout hits carry Early Access + Immersive Sim + Realistic; a typical game here doesn't.
The era
The games you compared span 2015 to 2023, 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).
