The middle of these games

≈ 431k–1.3M copies

≈ $3.8M–$19.3M after Steam's cut

from ~11k 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: Stellaris at ≈ 8.2M–13.3M copies, ≈ $112.6M–$302.8M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering
Your set
Your set clusters on Sci-fi (8 of 8) and Space (8 of 8).
The winners
Winners here lead with Space + Grand Strategy, priced around $50. The breakout hits carry Exploration + Sandbox + Simulation; a typical game here doesn't.
The era
The games you compared span 2010 to 2024, and 1 of your 8 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).
