The middle of these games

≈ 434k–1.8M copies

≈ $1.4M–$5.4M after Steam's cut

from ~11k 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: ARK: Survival Evolved at ≈ 26.7M–43.4M copies, ≈ $110.1M–$296.0M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Dinosaurs (8 of 8) and Open World (5 of 8).
The winners: Winners here lead with Open World Survival Craft + Survival, priced around $15. The breakout hits carry Open World Survival Craft + Crafting + Building; a typical game here doesn't.
The era: The games you compared span 2011 to 2018, and none of them 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 38 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).
