≈ $91.2M after Steam's cut

from ~111k reviews

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

3 of your 8 similar games are hits.

Best case: ULTRAKILL at ≈ 6.0M–9.7M copies, ≈ $49.4M–$132.9M after Steam's cut.

What it took to get here

The games that made it here had under 33k reviews in their first month.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on FPS (8 of 8) and Arena Shooter (6 of 8).
The winners: Winners here lead with Boomer Shooter + Fast-Paced, priced around $30.
The era: Only 2 of your 8 similar games shipped in the last two years. That says more about your picks than about the market, so add newer similar games to read the timing.

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 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
