What it took to get here

About half the games that made it here had over 1k reviews in their first month; the spread ran 165 to 4k.

The genre you'd be entering

Your set: Your set clusters on Story Rich (6 of 8) and Psychological Horror (3 of 8).
The winners: Winners here lead with Visual Novel + Psychological Horror, priced around $6. The breakout hits carry Visual Novel + Experimental + Abstract; a typical game here doesn't.
The era: The games you compared span 2012 to 2023, 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).
