Your set: Your set clusters on Exploration (8 of 8) and Walking Simulator (6 of 8).
The winners: Winners here lead with Story Rich + Exploration, priced around $25. The breakout hits carry Story Rich + Adventure + Singleplayer; 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).
