Your set: Your set clusters on Co-op (5 of 8) and Rogue-lite (5 of 8).
The winners: Winners here lead with Co-op, priced around $22. The breakout hits carry Co-op; 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
