It is a difficult problem, but there have been a lot of cracked Denuvo games, even in this article, it mentions that about half of the released Denuvo games have been cracked out of a total of 127, that’s not a small amount.
It is true though that Denuvo is complex and there’s currently only one person who has been doing them for a bit and that person is presenting as very very mentally ill and may also be on a break… it’s amazing reading, but it’s hard to tell conclusively what’s up with Empress.
