Your set: Your set clusters on Horror (8 of 8) and Survival Horror (8 of 8).
The winners: Winners here lead with Horror + Survival Horror, priced around $20. The breakout hits carry Team-Based + Online Co-Op + Survival; a typical game here doesn't.

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).
