≈ 696k–2.4M copies

≈ $2.9M–$8.3M after Steam's cut

from ~27k reviews

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

All 8 of your similar games are hits.

Best case: The Binding of Isaac: Rebirth at ≈ 25.2M–41.0M copies, ≈ $104.0M–$279.6M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

The genre you'd be entering
Your set
Your set clusters on Action Roguelike (8 of 8) and Bullet Hell (5 of 8).
The winners
Winners here lead with Action Roguelike + Rogue-like, priced around $15. The breakout hits carry Replay Value + Great Soundtrack + Dungeon Crawler; a typical game here doesn't.
The era
The games you compared span 2014 to 2025, and 2 of your 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
