The winners: Winners here lead with Open World Survival Craft + Survival, priced around $30.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2020. That says more about which games were found than about the market.

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).
