A typical game among these

≈ 85k–125k copies

≈ $484k–$627k after Steam's cut

from ~2k 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.

Best case: Deep Rock Galactic: Survivor at ≈ 1.2M–2.0M copies, ≈ $4.3M–$11.6M after Steam's cut. It is a breakout hit, far above a typical game.

About half the games that made it here had over 16k reviews in their first month; the range was 2k to 41k.

The genre you'd be entering

These games: The similar games share Bullet Hell (8 of 8) and Top-Down Shooter (5 of 8).
The winners: Winners here lead with Bullet Hell + Action Roguelike, priced around $13. The breakout hits carry Action Roguelike + Rogue-lite; a typical game here doesn't.
When they shipped: The similar games span 2015 to 2026, and 2 of the 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
