The Sega CD attachment made it possible for CD-ROM based games and music playback for the Sega Genesis. The add-on was known for it’s large library of Full Motion Video (FMV) games. The North American release of the accessory was in 1992.
Fond memories of this on Christmas Morning. I ripped open a present,saw the Sega CD and yelled YEES!!! so loud I woke up the block! The console was so hyped because of the full motion video games aka FMV.
Sega CD introduced FMV games to console gamers.
Sonic CD. The end.
