What it took to get here

About half the games that made it here had over 33k reviews in their first month; the spread ran 55 to 76k.

The genre you'd be entering

Your set: Your set clusters on FPS (7 of 8) and Shooter (6 of 8).
The winners: Winners here lead with FPS + Shooter. The breakout hits carry Action + Team-Based; a typical game here doesn't.
The era: The games you compared span 2007 to 2022, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
