The genre you'd be entering

Your set: Your set clusters on Story Rich (8 of 8) and Visual Novel (6 of 8).
The winners: Winners here lead with Detective + Visual Novel, priced around $25. The breakout hits carry Detective + Anime + Mystery; 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 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
