"Quest 64, released as Holy Magic Century in Europe, Australia and New Zealand and as Eltale Monsters (エルテイル モンスターズ, Eruteiru Monsutāzu) in Japan, is a single-player role-playing game developed by Imagineer and published by THQ. It was released for the Nintendo 64 in 1998 and was the first RPG released for the system in the United States.
After Quest 64's moderate financial success, a sequel was in consideration by the developer Imagineer. However, only the sequel's story was revealed before it was ultimately cancelled. Imagineer released two other related games for the Game Boy Color: Quest RPG: Brian's Journey and a puzzle game called Quest: Fantasy Challenge."
