≈ 326–8k copies

≈ $1k–$50k after Steam's cut

from ~53 reviews

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

2 of the 8 similar games are hits.

Best case: A Dance of Fire and Ice at ≈ 2.4M–3.9M copies, ≈ $4.0M–$10.7M after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like
About half the games that made it here had over 31 reviews in their first month; the range was 2 to 74.
Games with under about 100 reviews in month one almost never recover.
The genre you'd be entering
These games
The similar games share Rhythm (7 of 8) and Electronic Music (3 of 8).
The winners
Winners here lead with Rhythm + Music, priced around $6. The breakout hits carry Difficult + Level Editor + Singleplayer; a typical game here doesn't.
When they shipped
The similar games span 2017 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
