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.

No genre covers most of your similar games. The closest is Horror (3 of 8), so the genre you lead with is still undecided.

Best case: Dead by Daylight at ≈ 38.8M–63.1M copies, ≈ $213.5M–$574.0M 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 Horror (3 of 8) and Platformer (3 of 8).
The winners: Winners here lead with Story Rich + Choices Matter, priced around $10. The breakout hits carry Gore; a typical game here doesn't.
The era: The games you compared span 2015 to 2023, 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
