Final Fantasy 15 Windows Edition will make use of the much-unloved Denuvo anti-tampering software to protect it against early-days piracy when it launches tomorrow. In spite of that, according to threads on Resetera and Reddit, it's already been cracked. 

This isn't a conventional crack, however, but more of a dodge. According to the notes published by Chinese cracking group 3DM (the outfit that claimed a couple of years ago that it was going on hiatus because Denuvo had become all but uncrackable), it was actually enabled by the EXE file from the demo, which was not protected by Denuvo. With a little bit of fiddling, it apparently works in conjunction with the preload files to bust things wide open.
