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: A Link Between Worlds
Shikata proposed the idea of Link having the ability to enter and merge onto walls; this feature would eventually become one of the title's unique gameplay aspects. Within a day, Mouri had created an initial prototype to demonstrate the feature, and seeing it in action led to an influx of ideas. Link was able to transform from a 3D character to a 2D character by entering walls, and then move smoothly around corners to reach places he previously could not. This ability opened up possibilities for creating new puzzles and using new mechanics. At this stage in the project, they still considered the game an extension of the DS "Zelda" games and used the same viewpoint and design of Link from "Spirit Tracks". Around October 2010, the prototype was presented to Miyamoto, who approved of the new concept. However, within two weeks of entering production, core members of the development team were reassigned to work on launch games for Nintendo's Wii U console which was scheduled for release in 2012. With the team disbanded, development ceased.
