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.
Satellaview games from The Legend of Zelda series
From the earliest days of the Satellaview, the intention was to provide an opportunity for players "from Kyūshū to Hokkaidō" to enjoy two-way communication and involvement with a communication system allowing multiplayer netplay. While the earliest broadcasts for the Satellaview included solo-play games and strictly time-linked SoundLink Magazines that gave a sense of the player's direct temporal connection to the broadcasting center, St.GIGA, Nintendo's goal of simultaneous involvement between and amongst players was thought to be lacking. For this reason Nintendo began sponsoring a series of student networking projects to develop a network game that would let home consumers interact with each other over the satellite broadcasting system. The result of this networking project was the world's first integrated radio-game (or SoundLink Game) - "BS Zelda".
