Commodore was trying to innovate which is always a risk. How optical disks would be used for "multimedia" was an experimental field. People expected the disks would be mainly used for reference works like encyclopedias and educational titles with narration and a bit of animation or music here and there, decent full motion video wasn't yet an option at an affordable price. Few games would justify the use of a CD yet as they weren't big enough and the Amiga graphics were more than good enough for the reference/education titles. Philips was trying to do the same with CDi but it turned out people weren't ready for "multimedia" in the living room and wouldn't be until around a decade later when DVD would take off with the killer app, quality movies. CD "multimedia" was a short lived thing on PCs before the internet exploded and consigned CD software to games and install disks. People didn't want to read "books" from a screen until the screens were small, light, held in the hand and paper like with the books being downloaded.
