The middle of these games

≈ 104k–141k copies

≈ $777k–$1.3M after Steam's cut

from ~3k reviews

7 of your 8 similar games are hits.

Best case: Loop Hero at ≈ 905k–1.5M copies, ≈ $3.7M–$10.0M 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 2k reviews in their first month; the spread ran 2 to 15k.

The genre you'd be entering

Your set: Your set clusters on Simulation (5 of 8) and Space (5 of 8).
The winners: Winners here lead with Sandbox + Space, priced around $22. The breakout hits carry Physics + Destruction + Realistic; a typical game here doesn't.
The era: The games you compared span 2011 to 2026, and 2 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).
