Kingdom Hearts

Kingdom Hearts is a 2002 action, role-playing game featuring Disney and Final Fantasy characters for Play Station 1.

The universe of Kingdom Hearts is a collection of various levels, referred to as "worlds", through which the player must progress. Thirteen can be accessed in the game and one, Disney Castle, is shown in cutscenes. Additional worlds are mentioned by various characters, but are inaccessible because they have been destroyed by the Heartless, beings of darkness. Ten of the worlds are based on Disney fiction and the other four were created by Square specifically for the game.

The graphics and characters of each world were designed to resemble the artwork style of its respective Disney film. Each Disney world is inhabited by characters from their respective film; Hercules and Philoctetes inhabit Olympus Coliseum, while Aladdin, Princess Jasmin, and Jafar inhabit Agrabah. Each world is disconnected from the others and exists separately. Most characters in the worlds are unaware of the other worlds' existence, with few exceptions. Players travel from one world to another via Gummi Ship.

The worlds created specifically for the game mirror the overall appearance of the other worlds and feature either new characters or characters from several Final Fantasy games. The new worlds include: Destiny Islands, where the story opens; Traverse Town, which serves as a launching point for most of the game; Hollow Bastion, which many of the Final Fantasy characters call home; and End of the World, a large, dark world created from the remnants of various worlds consumed by the Heartless. The main characters travel from world to world to seal each "Keyhole"; this protects the world from the Heartless and ultimately from destruction. They also try to minimize their interaction with characters of other worlds to maintain a balance of separation. This sometimes requires Sora, Donald, and Goofy to blend in with the world inhabitants by changing their physical appearance.

Plot (In English, lol)

Sora and his friends, Riku and Kairi, live on an island (supposedly a world) called Destiny Islands.
They are about to set off on a quest to find other worlds. Their wish is granted.
The night before they are to take off, Heartless invade their world and completely consume it, taking Sora, Riku and Kairi along with it, thus separating the group.

Meanwhile, back at Disney Castle, Donald Duck, Goofy, Queen Minnie and Daisy have discovered their beloved King Mickey has gone missing and thus Donald, Goofy and the trusty Jiminy Cricket set off to find him, with the help of Pluto.

Sora wakes up in a town called Traverse Town, completely dazed and unaware of his world's sad consumption.
Back on the island, he had mysteriously ended up with a strange key-like blade called the Keyblade, which he fought the endless swarms of Heartless with, until he decided to go find his friends.

Unaware of Donald and Goofy being in the same place as he, Sora looks around the town to see what he could find.

Soon, he finds out, by Squall Leonhart, Yuffie Kisaragi and Aerith Gainsborough, that he is the chosen Keyblade master and that he was meant to save the worlds from the hands of the Heartless, by sealing the worlds' "keyhole."
After fighting more Heartless and looking around the town, he ends up with Donald and Goofy and they fight against the world's primary Heartless boss, Guard Armor.

After defeating him, they decide to team up to find King Mickey, Riku and Kairi.
And thus the journey begins.
