The genre you'd be entering

These games: The similar games share Simulation (7 of 8) and Management (6 of 8).
The winners: Winners here lead with Driving + Transportation, priced around $20. The breakout hits carry Driving + Transportation + Automobile Sim; a typical game here doesn't.

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).
