Welcome to the Spin off Zelda games section. The following titles although all official Zelda games do not fall under the canon of the main series Adventure/RPG style, or tie in with it's storylines. Both Link's Crossbow Training and Hyrule Warrior's are standalone non RPG/Adventure titles so easily fell into this category.
Titles such as Link: The Faces of Evil, Zelda: The Wand of Gamelon and Zelda's Adventure although they were Adventure/RPG titles were not produced by Nintendo and strayed quite far from the beaten track, leaving them isolated from the canon of the main series of games.
