Games like Symphony of Souls

A typical game among these

≈ 1k–3k copies

≈ $5k–$12k after Steam's cut

from ~44 reviews

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

1 of the 8 similar games is a hit.

No genre covers most of these similar games. The closest is Platformer (4 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Hi-Fi RUSH at ≈ 893k–1.5M copies, ≈ $7.4M–$19.8M 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 26 reviews in their first month; the range was 9 to 11k.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Platformer (4 of 8) and Rhythm (4 of 8).
The winners: Winners here lead with Rhythm + Hack and Slash, priced around $30. The breakout hits carry Hack and Slash + Great Soundtrack + Singleplayer; a typical game here doesn't.
When they shipped: The similar games span 2019 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 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
