The genre you'd be entering

Your set: Your set clusters on Open World (5 of 8) and Superhero (5 of 8).
The winners: Winners here lead with Open World, priced around $40. The breakout hits carry Open World + Western + Realistic; a typical game here doesn't.
The era: The games you compared span 2009 to 2024, and 1 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
