Phantasmagoria is an interactive movie point-and-click adventure game created by Sierra On-line for the PC, and later for the Sega Saturn in Japan. The game was released in 1995 and was followed by a sequel, Phantasmagoria: A Puzzle of Flesh in 1996.
Made during the height of the "interactive movie" boom in the computer game industry, Phantasmagoria is notable for being the first game to use a live actor (Victoria Morsell) as an on-screen avatar. The game was released on seven CDs to accommodate the massive amount of video generated by this process, the creation of which was contracted by Sierra to Kronos Digital Entertainment (who had previously worked on Sierra's King's Quest VI). Large portions of data were repeated on each CD, to avoid in-game disc swapping.
