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

The genre you'd be entering
Your set
Your set clusters on Historical (7 of 8) and Naval (6 of 8).
The winners
Winners here lead with Naval Combat + Co-op, priced around $40. The breakout hits carry Multiplayer + Grand Strategy; a typical game here doesn't.
The era
The games you compared span 2008 to 2022, 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).
