Action role-playing game
An important influence on the action RPG genre was the 1986 action-adventure, "The Legend of Zelda", which served as the template for many future action RPGs. In contrast to previous action RPGs, such as "Dragon Slayer" and "Hydlide," which required the player to bump into enemies in order to attack them, "The Legend of Zelda" featured an attack button that animates a sword swing or projectile attack on the screen. It was also an early example of open-world, nonlinear gameplay, and introduced new features such as battery backup saving. These elements have been used in many action RPGs since.
The Legend of Zelda
The next "Legend of Zelda" for the DS, "", was released in December 2009. In this game, the 'spirit tracks', railroads which chain an ancient evil, are disappearing from Hyrule. Zelda and Link go to the 'Spirit Tower' (the ethereal point of convergence for the tracks) to find out why. But villains steal Zelda's body for the resurrection of the Demon King. Rendered disembodied, Zelda is left a spirit, and only Link (and a certain few sages) can see her. Together they go on a quest to restore the spirit tracks, defeat the Demon King, and return Zelda to her body. Using a modified engine of that used in "Phantom Hourglass", the notably new feature in this game is that the Phantom Guardians seen in "Phantom Hourglass" are, through a series of events, periodically controllable. It was the first time in the series that both Link & Zelda work together on the quest.
