Games like King of Seas

A typical game among these

≈ 134k–433k copies

≈ $1.4M–$3.7M after Steam's cut

from ~5k 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: Assassin’s Creed® IV Black Flag™ at ≈ 1.9M–3.2M copies, ≈ $21.4M–$57.7M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 814 reviews in their first month; the range was 483 to 5k.

The genre you'd be entering

These games: The similar games share Pirates (8 of 8) and Naval Combat (5 of 8).
The winners: Winners here lead with Pirates + Open World, priced around $40. The breakout hits carry Assassin + Stealth + Parkour; a typical game here doesn't.
When they shipped: 4 of the 7 similar games shipped in the last two years, so this genre is actively shipping.

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).
