The genre you'd be entering
Your set
Your set clusters on Simulation (5 of 8) and Zombies (5 of 8).
The winners
Winners here lead with Zombies, priced around $22. The breakout hits carry Multiplayer + Zombies + Online Co-Op; a typical game here doesn't.
The era
The games you compared span 2015 to 2026, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
