Games like HAYAI

A typical game among these

≈ 649k–1.5M copies

≈ $1.1M–$7.2M after Steam's cut

from ~25k reviews

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.

Best case: Vampire Survivors at ≈ 6.6M–10.7M copies, ≈ $9.1M–$24.4M 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 20k reviews in their first month; the range was 926 to 129k.

The genre you'd be entering

These games: The similar games share Action Roguelike (5 of 8) and Bullet Hell (4 of 8).
The winners: Winners here lead with Action Roguelike + Bullet Hell, priced around $5. The breakout hits carry Vampire + Pixel Graphics + 2D; a typical game here doesn't.
When they shipped: The similar games span 2012 to 2025, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
