Fun Fact: The Gurus who served as save points in Faxanadu displayed Christian iconography in the Japanese release, all of which was stripped for the international release.
Faxanadu is always compared to Zelda II: The Adventure of Link on account of being a platform RPG. Players took control of an Elven warrior who had to confront an evil force dwelling within the World Tree, and which had poisoned the land's water supply.
Faxanadu was actually much darker than Zelda II in both visuals and audio design, and felt more akin to the Castlevania series in mood. In the eyes of many critics, Faxanadu did not receive its due recognition in the pantheon of NES games.
