The winners: Winners here lead with Visual Novel + Psychological Horror, priced around $1. The breakout hits carry Psychological Horror + Horror + Experimental; a typical game here doesn't.

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
