I've seen many CD-ROM retrospectives that credit Myst and The 7th Guest (both 1993) as the "first CD-ROM game" or "first CD-ROM adventure". Other sources may cite games a year or two earlier, or into the 80s, but there's little consistency in the definition of what a "CD-ROM game" even is. Is it any game on a CD-ROM? Is it a game created first or solely for CD-ROM, or does a CD version of a floppy game count? Does it only count computer games and not console games?
