I remember playing a demo unit of a CD-i at Rich's while my mom shopped (this was back when department stores still had electronics departments). Whatever game they had available on it was so boring that it was only slightly better than following her around looking at clothes. I also remember, at other times in the same place, playing Sonic on Genesis and messing around with MS Paint on a Windows 3.1 PC. Of the three experiences, the CD-i experience was by far the least fun.
