> Allegedly they have a custom approach to each new game, so cracks can take months to appear

It's because it's tedious to crack it, it's not really a rocket science, they just generate new VM for the binary so you can't automate it, they inject A LOT of code paths which you need to manually follow and change. That's the only reason why games stay uncracked for months. It's a war of attrition.

> with some unpopular games never having been cracked at all

That's not exactly true actually, you need to pay for Denuvo license every year, that's why after some months or a few years it's removed from most of the games.
