The middle of these games

≈ 3.7M–5.8M copies

≈ $48.2M–$58.8M after Steam's cut

from ~93k 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: People Playground at ≈ 9.1M–14.9M copies, ≈ $25.1M–$67.5M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Sandbox (6 of 8) and Simulation (5 of 8).
The winners: Winners here lead with Sandbox, priced around $20. The breakout hits carry Moddable + Singleplayer; a typical game here doesn't.
The era: None of the games you compared shipped in the last two years; the newest is from 2020. That says more about your picks than about the market, so add newer similar games to read the timing.

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).
