Copies, estimated from reviews

typical (middle half) 9.4M–12.9M

Games like Eco

A typical game among these

≈ 9.4M–12.9M copies

≈ $108.2M–$205.5M after Steam's cut

from ~350k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

Best case: Rust at ≈ 42.7M–69.3M copies, ≈ $469.3M–$1261.8M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 182k reviews in their first month; the range was 86k to 327k.

The genre you'd be entering

These games: The similar games share Open World (7 of 8) and Survival (7 of 8).
The winners: Winners here lead with Open World Survival Craft + Survival, priced around $30. The breakout hits carry Building + Open World Survival Craft + Adventure; a typical game here doesn't.
When they shipped: The similar games span 2013 to 2024, and 3 of the 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).
