The winners: Winners here lead with Bullet Hell + Action Roguelike, priced around $15. The breakout hits carry Rogue-like + Dungeon Crawler + Local Co-Op; 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
