The music and the sound in Myst and Riven were both outstanding - absolute classics of the genre, and even more amazing given that they were an amateur effort by one of the creators, and not the work of a full-time composer or game sound designer.
There was one location in Riven where I spent about fifteen minutes listening to a short-ish music loop over and over and watching a simple atmospheric location animation, because both were just so perfect.
This really proves in the arts and creative business, it's really an individual's work that connects the souls. You can have a team of thousands of people, but if no one has any vision or creativity then their work can go straight down the toilet.
Even just the first minutes, the Cyan logo, and the introductory music, are etched into my brain. Every once in a while, despite the fact that I haven't played Myst in at least a decade, they'll just pop in my head.
