A typical game among these

≈ 764k–1.6M copies

≈ $3.5M–$12.2M after Steam's cut

from ~24k 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: My Summer Car at ≈ 2.9M–4.8M copies, ≈ $12.1M–$32.4M after Steam's cut. It is a breakout hit, far above a typical game.

About half the games that made it here had over 13k reviews in their first month; the range was 6k to 84k.

The genre you'd be entering

These games: The similar games share Simulation (6 of 8) and Building (5 of 8).
The winners: Winners here lead with Automobile Sim + Simulation, priced around $15. The breakout hits carry Automobile Sim + Driving + Open World; a typical game here doesn't.
When they shipped: The similar games span 2016 to 2025, and 1 of the 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
