The GDRI (Game Developer Research Institute) researches the history of video games and their creators. They recently picked up a few stories of Interactive Dreams. With that, a few new details pop up which are very interesting to investigate further. GDRI: "The manual for the Japanese version of CD-i The Renaissance of Florence credits Opera House with "production cooperation," whatever that means. Aya Nishitani, the author of Digital Devil Story: Megami Tensei, was also behind this rare Japanese CD-i title, Horoscope." Thanks to CD-i member Seventy7 and Blazers, we can all enjoy the CD-i title Horoscope. It seems this title has more historical significance than what was thought before. More when it develops.
