Both were remarkable for using MJPEG fullmotion video for basically everything and every node+transitions in the environment. In fact, even the still screens are merely frozen or looped MJPEG frames ww Quality and bloat

is to be expected but this was less intensive than MPEG would've been and could run on potato polack computers of the period fine. Easier to program too, since MJPEG is an intra-frame compression method.
As games, they are extremely puzzle oriented - think first Myst on steroids.
The screenshot is from a manual of a 1998 game by the way. That's one year into Intel's P6 architecture yet the game would run on Intel Pentium 75 from 1994 (albeit with choppy music since it was MP3-in-WAVE container)
