The middle of these games

≈ 3.1M–4.7M copies

≈ $36.8M–$53.1M after Steam's cut

from ~81k reviews

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

All 8 of your similar games are hits.

Best case: War Thunder at ≈ 49.3M–80.1M copies. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Simulation (6 of 8) and Building (3 of 8).
The winners: Winners here lead with Simulation + Vehicular Combat, priced around $20. The breakout hits carry Free to Play + Vehicular Combat + World War II; a typical game here doesn't.
The era: The games you compared span 2013 to 2020, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
