Your set: Your set clusters on Rogue-like (5 of 8) and Action Roguelike (4 of 8).
The winners: Winners here lead with Dwarf + Co-op, priced around $30. The breakout hits carry Dwarf + PvE + Class-Based; a typical game here doesn't.

How these numbers were worked out

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).
