The middle of these games

≈ $21.7M–$95.6M after Steam's cut

from ~122k 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: Garry's Mod at ≈ 79.8M–129.6M copies, ≈ $219.1M–$589.2M 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 49k reviews in their first month; the spread ran 31k to 122k.

The genre you'd be entering

Your set: Your set clusters on Sandbox (8 of 8) and Physics (7 of 8).
The winners: Winners here lead with Sandbox + Moddable, priced around $10. The breakout hits carry First-Person + Multiplayer + Casual; a typical game here doesn't.
The era: The games you compared span 2006 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).
