EarthBound features many traditional role-playing game elements: the player controls a party of characters who travel through the game's two-dimensional world composed of villages, cities, caves, and dungeons. Along the way, the player fights battles against enemies and the party receives experience points for victories. If enough experience points are acquired, a character's level will increase. This pseudo-randomly increases the character's attributes, such as offense, defense, and the maximum hit points (HP) and psychic points (PP) of each character. Rather than using an overworld map screen like most console RPGs of its era, the world is entirely seamless, with no differentiation between towns and the outside world. Another non-traditional element is the perspective used for the world. The game uses oblique projection, while most 2D RPGs use a "top-down" view on a grid or an isometric perspective.
