Perhaps I wasn't clear enough. What I meant was that Myst was the first adventure game that was neither inventory based nor dialogue based. The Loom and The 7th Guest did have no inventories, and technically they weren't dialogue based either (there weren't any dialogue trees that decided how the stories progressed), but they relied quite heavily on dialogues/monologues to advance the stories. In contrast, inventory and dialogues/monologues were almost non-existent in Myst, and the player wasn't told a background story at the outset. This was very unusual in that era. And I also didn't say that Myst was the first CD-ROM game. What I said was that Myst was the first game that was distributed entirely with CD-ROM. (Actually The 7th Guest was the first, but it and Myst were released in the same year. ) The Manhole, according to Wikipedia, was released on floppies first.
