Your set: Your set clusters on Bullet Hell (8 of 8) and Twin Stick Shooter (7 of 8).
The winners: Winners here lead with Rhythm + Music-Based Procedural Generation, priced around $10. The breakout hits carry 2D + Rhythm + Music-Based Procedural Generation; a typical game here doesn't.

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).
