One of the first games that used the CD-ROM format (and also one of the first ones that featured voice acting), Bikkuriman Daijikai is a quiz game dedicated entirely to the popular Bikkuriman franchise, which originated with stickers on chocolate bars, and later evolved into collectible card game, manga and anime series.
Each "head" unlocks a map part of the Bikkuriman world; each part, in its turn, unlocks a series of short non-interactive scenes from the anime, accompanied by narration.
