Role-playing video game
Typically action RPGs feature each player directly controlling a single character in real time, and feature a strong focus on combat and action with plot and character interaction kept to a minimum. Early action RPGs tended to follow the template set by 1980s Nihon Falcom titles such as the "Dragon Slayer" and "Ys" series, which feature hack and slash combat where the player character's movements and actions are controlled directly, using a keyboard or game controller, rather than using menus. This formula was refined by the action-adventure game, "The Legend of Zelda" (1986), which set the template used by many subsequent action RPGs, including innovations such as an open world, nonlinear gameplay, battery backup saving, and an attack button that animates a sword swing or projectile attack on the screen. The game was largely responsible for the surge of action-oriented RPGs released since the late 1980s, both in Japan and North America. "The Legend of Zelda" series would continue to exert an influence on the transition of both console and computer RPGs from stat-heavy, turn-based combat towards real-time action combat in the following decades.
Overworld
While previous games have featured overworlds, one of the earliest console games to feature an overworld is the Nintendo Entertainment System game "The Legend of Zelda". Gameplay in "Zelda"s overworld was virtually identical to that of its nine underground dungeon levels, offering a top-down perspective and including access to caves, bridges, mazes, shops and waterfalls as well as lurking dangers that range from enemies to tumbling rocks. Much of the immediate gameplay takes place in the overworld, and the diversity of terrain (as well as the sheer size of the overworld itself) ensures that the player will spend as much time exploring and searching above ground as they will below (or in any of the areas listed above). The concept of an overworld also offered a nonlinear gameplay experience; some believed this would cause the player to become confused and not know where to go, a sentiment which has endured as overworlds have become larger and more complex.
