≈ 101k–130k copies

≈ $299k–$625k after Steam's cut

from ~3k reviews

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: Brotato at ≈ 2.9M–4.8M copies, ≈ $4.0M–$10.8M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 2k reviews in their first month; the spread ran 537 to 42k.

The genre you'd be entering

Your set: Your set clusters on Top-Down Shooter (5 of 8) and Bullet Hell (4 of 8).
The winners: Winners here lead with Action Roguelike + Bullet Hell, priced around $9. The breakout hits carry Arena Shooter + Action Roguelike + Bullet Hell; a typical game here doesn't.
The era: The games you compared span 2014 to 2025, 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
