Games like Demonologist

The middle of these games

≈ 28.4M–69.2M copies

≈ $210.7M–$337.9M after Steam's cut

from ~838k 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: PUBG: BATTLEGROUNDS at ≈ 94.5M–153.6M copies. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Survival (5 of 8) and Co-op (4 of 8).
The winners: Winners here lead with Survival + Shooter. The breakout hits carry Third-Person Shooter + Battle Royale + PvP; a typical game here doesn't.
The era: The games you compared span 2009 to 2020, 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 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).
