That sounds familiar. I'm still racking my brains trying to remember that first CDROM game. I can see the ads for it in my head. Damn you.
Take your time, no rush

I googled a bit for this one. Turns out it was also a project of Roberta Williams.

King's Quest V - Absence Makes the Heart Go Yonder changed the graphical adventure game in a major way. Although criticized by old adventure game fans who claimed the removal of the parser interface "dumbed down" the game, this new interface prevailed and became the new standard for adventure games. The gameplay of King's Quest V had some flaws, but with its hand-drawn 256-color graphics King's Quest V looked far better than any competing game on the market. It was the first Sierra game to sell more than 500,000 copies and it won several awards.

Constantly thriving to lead the way in utilizing the latest technology, Sierra decided to produce the first game ever on CD-ROM, supporting the Microsoft Windows multimedia features. This game was to be Mixed-Up Mother Goose, in an enhanced version with 256 colors and real speech instead of text. The voices in the game were performed by Sierra employees, including Roberta Williams herself. Due to little or no acting experience the end result didn't sound very professional, but it did the job. The game was a technological nightmare to complete, but its release in 1990 earned it the Best Early Education Award from the Software Publishers Association. Sierra went on to release an enhanced multimedia version of King's Quest V on CD too.
