All 8 of your similar games are hits.

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

The genre you'd be entering

Your set: Your set clusters on Bullet Hell (8 of 8) and Arcade (6 of 8).
The winners: Winners here lead with Bullet Hell, priced around $7. The breakout hits carry Action + 2D + Great Soundtrack; a typical game here doesn't.
The era: The games you compared span 2011 to 2022, and none of them 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).
