The genre you'd be entering

Your set: Your set clusters on Simulation (8 of 8) and Farming Sim (7 of 8).
The winners: Winners here lead with Farming Sim + Life Sim, priced around $15. The breakout hits carry Pixel Graphics + Relaxing + Life Sim; a typical game here doesn't.
The era: The games you compared span 2016 to 2024, and 2 of your 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 52 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
