The genre you'd be entering

These games: The similar games share Building (8 of 8) and Crafting (8 of 8).
The winners: Winners here lead with Building + Sandbox, priced around $29. The breakout hits carry Base-Building + Physics; a typical game here doesn't.
When they shipped: The similar games span 2014 to 2026, and 1 of the 8 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
