Game developer and blogger Fabien Sanglard explains why id Software's 1996 Quake CD-ROM, which encrypted the full game catalog, was cracked in 39 days. The shareware experiment failed, leaving about 150,000 CDs unsold, according to the book Masters of Doom.
When id Software shipped Quake in 1996, the full game was only about 23MB, leaving most of the CD-ROM empty. To fill the space, the developers encrypted their entire catalog on the disc, letting players pay by phone to unlock each title.
The scheme lasted 39 days. The hacker group GNOMON released Quakecrk.zip, a tool that decrypted every game on the disc. According to the book Masters of Doom, the experiment ended in failure, with roughly 150,000 CDs left in a warehouse.
