I'm telling you, if there's a cracker interested enough with plenty of spare time, SH5 will be cracked. I like to have contacts around, and I'm being told that nowadays, games are being cracked even before they're released, about 99% of protected games
can be cracked (as opposed to "will actually be cracked"). Even Steam was cracked. I didn't believe it myself until I saw live proof of it (I ain't telling you how to make it, though

).
Interest on the subject in question (passion for it, the will to archieve the goal), and spare time. With these 2, ALMOST ANYTHING can be cracked. And note I'm not justifying anything on piracy, I'm just telling you what the reality is, just like it's also reality that the modern world is becoming a worse place because of the financial crisis.
Cheers.
