The winners: Winners here lead with Sandbox + Simulation, priced around $20.
When they shipped: The similar games span 2015 to 2022, and none of them shipped in the last two years.

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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
