≈ $4.9M after Steam's cut

from ~39k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

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

The genre you'd be entering

These games: The similar games share 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.
When they shipped: The similar games 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).
