≈ $198–$405 after Steam's cut

from ~8 reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

3 of your 8 similar games are hits.

Your picks lean toward this genre's biggest survivors; the typical figure reads from its ordinary successes.

Best case: Vampire Survivors at ≈ 6.6M–10.7M copies, ≈ $9.0M–$24.2M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 11 reviews in their first month; the spread ran 2 to 129k.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on Action Roguelike (8 of 8) and Bullet Hell (8 of 8).
The winners: Winners here lead with Bullet Hell + Action Roguelike, priced around $11. The breakout hits carry Difficult + Indie + Twin Stick Shooter; a typical game here doesn't.
The era: 4 of your 8 similar games shipped in the last two years, so this niche 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
