Kingdom Hearts (series)

Kingdom Hearts (キングダムハーツ, Kingudamu Hātsu?) is a series of action role-playing games developed and published by Square Enix (formerly Square). It is the result of a collaboration between Square and Disney Interactive Studios and is under the direction of Tetsuya Nomura, a longtime Square character designer. Kingdom Hearts is a crossover of various Disney settings based in a universe made specifically for the series. In addition, it has an all-star voice cast which includes many of the Disney characters' official voice actors. Characters from Square Enix's Final Fantasy series make appearances and interact with the player and Disney characters. The series centers around the main character Sora's search for his friends and his encounters with Disney and Final Fantasy characters on their worlds.

The Kingdom Hearts series currently consists of four games across different video game platforms, and future titles are planned. Most of the games in the series have been both critically acclaimed and commercially successful, though each installment has seen varying levels of success. As of December 2006, the Kingdom Hearts series has shipped over ten million copies worldwide, with 2.0 million copies in PAL regions, 3.0 million copies in Japan, and 5.6 million copies in North America. There have been several types of merchandise released along with the games, such as soundtracks, figurines, and companion books. In addition, the games have also been adapted into a manga series and novels.

Overview
Further information: Characters of Kingdom Hearts

Kingdom Hearts features a mixture of familiar Disney and Final Fantasy characters, as well as several new characters designed and created by Nomura. Though the series features locations unique to the Kingdom Hearts franchise, worlds from Disney films are heavily explored. Sora must visit these worlds and interact with popular Disney characters to protect them from enemies. Often, Sora's actions in these worlds follow closely to the storylines featured in their accompanying Disney films. In dialogue, Donald Duck tells Sora not to interfere with the worlds too much, since it would cause problems. Moogles, small creatures from Final Fantasy, are another common element in the games. They provide the player with a synthesis shop in order to create items for use in the game.

Gameplay
The Kingdom Hearts series games contain elements from both action and role-playing games. The games are driven by a linear progression to the next story event, usually told in the form of a cut scene, though there are numerous side quests available that provide bonus benefits to the characters. The player is primarily in control of the principal protagonist of the series, Sora. Sora is usually accompanied by Donald Duck and Goofy, who are non-playable characters that aid Sora in battle. In the first and third game, their behavior could be altered to fit the player's needs. The games featured real-time combat that incorporates physical attacks, magic, and summonings; though each game handled battles differently.

Gummi Ships are another common theme in the series, though they are only featured in the first and third installment. The Gummi Ships serve as the main mode of transportation between worlds in the games. The gameplay for the Gummi Ships sections is more akin to a rail shooter. Because it received negative criticism in the first game, it was improved in the third installment. All three games also feature a journal which is accessible from the main menu. The journal keeps track of information regarding the story, characters, enemies, and locations. In the game the journal is kept by Jiminy Cricket, who was appointed by Queen Minnie as the royal chronicler.

The games are influenced by their parent franchise, Final Fantasy, and carry its gameplay elements over into their own action-based, hack-and-slash system. Like many traditional role-playing games, Kingdom Hearts features an experience point system which determines character development. As enemies are defeated, the player gains experience which culminate in a "level-up", where the characters grow stronger and gain access to new abilities. The amount of experience is shared with all party members and each character grows stronger as experience is gained.

Story
The three main games in Kingdom Hearts series focus on the adventures of Sora and his search for his friends, Kairi and Riku. The first game shows how Sora is separated from his friends when their world is invaded by an army of corrupted hearts known as the Heartless. During the invasion, he obtains a special weapon known as a Keyblade. Soon after, Sora meets Donald Duck, the Disney Castle court magician, and Goofy, the Disney Castle captain of the royal guard. Donald and Goofy are searching for the "key" per instructions from King Mickey. The three band together and travel to different Disney themed worlds, sealing the hearts of the worlds to prevent more Heartless invasions. Along the way they encounter a group of Disney villains, led by Maleficent, that are controlling the Heartless. The three eventually discover that a man named Ansem is the true antagonist. Ansem's plan is to open the door to Kingdom Hearts. Sora, Donald, and Goofy defeat Ansem, and seal the door with the help of Riku and King Mickey on the other side of the door.

After sealing the door to Kingdom Hearts, the three begin searching for Riku and King Mickey. They encounter a mysterious fortress called Castle Oblivion. Upon entering the fortress, they begin to lose their memories. The three encounter a group of dark hooded villains referred to as the Organization. After defeating the Organization members in the castle, Sora learns his memories have been manipulated by a girl named Naminé who is controlled by the Organization. To allow them to regain their memories, Naminé puts Sora, Donald, and Goofy to sleep for a year. While the three are ascending to the top floor of the castle, Riku and King Mickey arrive in the basement and began traveling to the top as well. Riku fights the darkness in his heart and learns to accept his dual nature between light and dark.

A year later, Sora, Donald, and Goofy awaken and continue their search for Riku and King Mickey. They learn of the Nobodies and their leaders, Organization XIII. Afterwards, Maleficent is resurrected and joins with Pete, another Disney villain, to continue her quest for power. Sora once again travels to many Disney-themed worlds and resolves the troubles caused by Organization XIII, the Heartless, Maleficent and Pete, and local villains. Meanwhile, Kairi is kidnapped by the Organization. They meet King Mickey, who reveals the true nature of Ansem, the antagonist of Kingdom Hearts. The Ansem who Sora defeated was actually the Heartless of Xehanort, a student of Ansem the Wise. Xemnas, the leader of Organization XIII, reveals himself to be the Nobody of Xehanort. The three arrive at the headquarters of Organization XIII, with Kingdom Hearts looming overhead. Ansem the Wise uses a device that dissipates some of Kingdom Hearts' power, but a system overload causes the machine to explode and kill Ansem. At the top of Organization XIII's castle, Sora and his friends battle Xemnas, who uses the remnants of Kingdom Hearts to fight them. After Xemnas' death, Sora and Riku are reunited with their friends at Destiny Islands, their home.

Time Line
The events in Kingdom Hearts: Birth by Sleep occurred 10 years before Kingdom Hearts. Kingdom Hearts: Chain of Memories and Kingdom Hearts 358/2 Days followed, somewhat simultaneously. Kingdom Hearts II started approximately one year after Sora's first adventure (and presumeably a few days after the culmination of Kingdom Hearts 358/2 Days). Finally, Kingdom Hearts coded.
