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.

Although noting some similarity to "Adventure", IGN UK argues that "The Legend of Zelda" (1986) "helped to establish a new subgenre of action-adventure", becoming a success due to how it combined elements from different genres to create a compelling hybrid, including exploration, adventure-style inventory puzzles, an action component, a monetary system, and simplified RPG-style level building without the experience points. "The Legend of Zelda" was the most prolific action-adventure game series through to the 2000s.
