The genre you'd be entering

Your set: Your set clusters on Simulation (5 of 8) and Flight (4 of 8).
The winners: Winners here lead with Sandbox + Base-Building, priced around $25.
The era: None of the games you compared shipped in the last two years; the newest is from 2023. That says more about your picks than about the market, so add newer similar games to read the timing.

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 38 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
