The middle of these games

≈ 478k–945k copies

≈ $4.8M–$9.3M after Steam's cut

from ~15k 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: Dyson Sphere Program at ≈ 2.3M–3.7M copies, ≈ $12.5M–$33.6M 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 13k reviews in their first month; the spread ran 4k to 26k.

The genre you'd be entering

Your set: Your set clusters on Simulation (5 of 8) and Sandbox (4 of 8).
The winners: Winners here lead with Automation + Space, priced around $20. The breakout hits carry Automation + Resource Management + Base-Building; a typical game here doesn't.
The era: The games you compared span 2012 to 2026, 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).
