Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on VR (5 of 8) and Co-op (3 of 8).
The winners: Winners here lead with Horror + Psychological Horror, priced around $20.
The era: The games you compared span 2017 to 2024, and 1 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
