The genre you'd be entering

The winners: Winners here lead with Sandbox + Gore, priced around $10. The breakout hits carry Sandbox + Moddable + 2D; a typical game here doesn't.
When they shipped: The similar games span 2015 to 2023, and none of them shipped in the last two years.

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