≈ 100k–113k copies

≈ $454k–$614k after Steam's cut

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.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

Best case: Soulstone Survivors at ≈ 668k–1.1M copies, ≈ $2.8M–$7.4M after Steam's cut. It is a breakout hit, far above a typical game.

About half the games that made it here had over 2k reviews in their first month; the range was 779 to 23k.

The genre you'd be entering

These games: The similar games share Bullet Hell (7 of 8) and Action Roguelike (4 of 8).
The winners: Winners here lead with Action Roguelike + Bullet Hell, priced around $12. The breakout hits carry Arcade; a typical game here doesn't.
When they shipped: 4 of the 8 similar games shipped in the last two years, so this genre is actively shipping.

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).
