"Myst" coming out on a CD at the time struck me as a very risky move as so few people had optical drives on their PCs. What I failed to appreciate (and why I must suck at marketing) is that everyone with a CD-ROM drive bought the game. You almost had to either to justify the device or perhaps to lord it over those who did not have one.
Myst's 1994 Windows release is pretty far into the CD-ROM era. I was playing Monkey Island with its great CD soundtrack in 92, and the talkie versions of Fate of Atlantis and King's Quest 6 in 93, for example.
For my friends, they lorded their CD-ROM drive with the purchase of Phantasmagoria. No time for those wimpy Myst games. My friends needed hardcore dramatic depictions of sexual violence.
