Hyrule Warriors isn't a Legend of Zelda game. Nor is it really a Nintendo game. Hyrule Warriors is a collaboration between Nintendo and two outside studios: Team Ninja, the studio behind Dead or Alive and Ninja Gaiden, and Omega Force, creators of the Dynasty Warriors series.
Instead of the traditional puzzle-solving and exploration focus of the Zelda games, Hyrule Warriors features hack-and-slash gameplay that defines titles like Dynasty Warriors. As a sort of mash-up, Hyrule Warriors takes that action gameplay and layers on top settings, characters and themes lifted from nearly three decades of Zelda history."
