Equally you miss out the biggest issue with most developments with CD-I the available disk speed and memory (even ignoring seek times) made most developments an interest combination of careful design and often luck. Watching that Mario interstitial with moving eyebrows I'm imaging the disk spinning desperately trying to load the next scene into memory. As an example I remember spending a week trying to work out how to minimise a MPEG video (quarter screen max) in such a way that we could run a seek and load up the background image ready for the next scene.
