Your set: Your set clusters on Action Roguelike (8 of 8) and Bullet Hell (6 of 8).
The winners: Winners here lead with Action Roguelike + Bullet Hell, priced around $5. The breakout hits carry Singleplayer + Vampire + Sci-fi; 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).
