The middle of these games

≈ 643–17k copies

≈ $701–$101k after Steam's cut

from ~55 reviews

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

2 of your 8 similar games are hits.

Best case: Stellaris at ≈ 8.2M–13.3M copies, ≈ $112.7M–$303.1M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 12 reviews in their first month; the spread ran 3 to 686.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Simulation (6 of 8) and Sandbox (5 of 8).
The winners: Winners here lead with Space + Sandbox, priced around $45. The breakout hits carry Space + Grand Strategy + Sci-fi; a typical game here doesn't.
The era: The games you compared span 2015 to 2023, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
