and smaller items such as keys and equipment. In later games, the dungeon includes a special "big key" that will unlock the door to battle the dungeon's boss enemy and open the item chest. In most Zelda games, the player's HP or life meter is represented by a line of hearts, each heart typically representing two hit points. At the start of the game the player only has three hearts but players can increase their max hearts by finding heart-shaped crystals called "Heart Containers". Full heart containers are usually received at the end of dungeons and dropped by dungeon bosses. Smaller "Pieces of Heart" are awarded for completing side quests or found hidden around the game world in various places, and require a certain number (usually four) to form a full heart container. Health can be replenished by picking up hearts left by defeated enemies or destroyed objects, consuming items such as potions or food, or going to a Great Fairy Fountain to have the Great Fairy heal Link completely. Occasionally the player will find fairies hidden in specific locations; these fairies can either heal Link immediately or be kept in empty bottles, and will revive the player the next time they die. The games pioneered a number of features that were to become industry standards. The original Legend of Zelda was the first console game with a save function that enabled players to stop playing and then resume later. The Legend of Zelda: Ocarina of Time introduced a targeting system that let the player lock the camera on to enemy or friendly NPCs which simplified 3D combat. Inspiration The Legend of Zelda was principally inspired by Shigeru Miyamoto's "explorations" as a young boy in the hillsides, forests, and caves surrounding his childhood home in Sonobe, Japan where he ventured into forests with secluded lakes, caves, and rural villages. According to Miyamoto, one of his most memorable experiences was the discovery of a cave entrance in the middle of the woods. After some hesitation, he apprehensively entered the cave, and explored its depths with the aid of a lantern. Miyamoto has referred to the creation of the Zelda games as an attempt to bring to life a "miniature garden" for players to play with in each game of the series. The story and setting was developed by Takashi Tezuka. Seeking to create a fairytale adventure game, Tezuka drew inspirations from
