A typical game among these

≈ 26k–70k copies

≈ $135k–$292k after Steam's cut

from ~857 reviews

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

4 of the 8 similar games are hits.

Best case: Beat Hazard at ≈ 471k–765k copies, ≈ $1.3M–$3.5M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Bullet Hell (8 of 8) and Twin Stick Shooter (7 of 8).
The winners: Winners here lead with Rhythm + Music-Based Procedural Generation, priced around $10. The breakout hits carry 2D + Rhythm + Music-Based Procedural Generation; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2024, and 1 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
