Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

Best case: ULTRAKILL at ≈ 6.0M–9.7M copies, ≈ $49.4M–$132.9M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on FPS (8 of 8) and Boomer Shooter (5 of 8).
The winners: Winners here lead with Boomer Shooter + Fast-Paced, priced around $30. The breakout hits carry Blood + Character Action Game + Arena Shooter; a typical game here doesn't.
The era: The games you compared span 2007 to 2023, 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).
