≈ $162.5M–$405.0M after Steam's cut

The winners: Winners here lead with Farming Sim + Life Sim, priced around $15.
When they shipped: The similar games span 2012 to 2018, 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 38 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).
