I think Empress disappearing would be a net-positive for the cracking scene.
If there is nobody cracking the latest releases, the pressure will mount for new crackers to enter the scene. And perhaps we’ll get a new generation of crackers that bring some competition back into the space.
There’s also a lot of money involved in pirated games, with shops in poorer countries selling cracked games for pennies on the dollar to people who would otherwise be unable to afford, or even download the latest games.
So it’s my opinion that denuvo cracking will never go away, it’ll just evolve over time, like it has since the beginning.
