Released on November 16, 1987 in Japan.
The title Faxanadu (pronounced as Fah San Ah Doo) is a 'portmanteau' of Famicom and Xanadu. This is because it is an unrelated side-quest story to Falcom's Xanadu RPG series.
Faxanadu employs a color palette that relies upon browns, greens, reds, and blues, creating an earthy atmosphere to complement the underlying, real-world legends of Elves, Dwarves, and the world tree itself. This was somewhat atypical compared to other games from its era, as many showcased bright, cartoonish graphics and outlined sprites rather than the more flushed, slightly Gothic style of Faxanadu. Similarly, the game's music is designed to convey a rich, sometimes haunting tone during play. From the pedestrian beat of Eolis and the majestic melody in the Elven King's throne room to the driving theme of The Evil One's fortress, the compositions are intended to set the mood for each area, assisted by an array of organic sound effects.
It is one of several Famicom games inspired by Zelda II, which also include Battle of Olympus and Moon Crystal.
Many aspects of the game's setting, especially the different shapes and forms of enemies, are largely inspired by a mixture of Norse mythology and Japanese mythology with some derivatives of Eastern religion, with several reminiscent of the works of H. R. Giger.
Christian icons found in the Japanese version are removed in the international releases. In the Japanese version, Gurus can be seen holding a Holy Cross and images of Jesus' crucifixion are displayed inside the churches.
Also, you can't rename your character in the export releases.
