Since I don't have the game yet I am going to rely on other's telling of the Kingdom Hearts story. ^_^ When I get the game I'll tell my version.

   The story of Kingdom Hearts has you taking the role of Sora, an ambitious boy who dreamt that he entered another world that had him trapped in a dark dimension where he would choose weaponry and then fight a gigantic beast of the underworld. After waking up, Sora meets up with his two best friends Riku and Kairi. Kairi wonders what her birthplace looks like, and suddenly the three of them decided to venture out and find out for themselves.

   For the first hour or two, the game will have you on Destiny Island, where you will encounter Tidus, Wakka, and Yuffie. You'll be able to duel them in practice fights, so that you get a hang of the game. As you make your way around Destiny Island, Kairi will ask you for some supplies to build a raft for the upcoming venture. As you get to the end of doing that, you will come across two cut-scenes, and this is where the story unravels.

   The second sequence introduces the Disney world, and presents Donald, Goofy, Pluto, Daisy Duck, and Minnie Mouse. Strange things are happening to Sora because he is the holder of the Keyblade. The Keyblade is a very important object in the game, and it also attracts minions of the dark world to Sora, so you will regularly have to fight them off.

   Shortly after a few sequence of events, you will end up meeting Squall and (spoiler!) Aerith. Following that, you will soon be partnered with Donald and Goofy, but only after you do some exploration in Traverse Town, the town in which you end up in after a chaotic event occurs back in Destiny Island. While the story seems a bit complex, it's really not. In fact, it's quite simple, and incredibly light hearted and pleasant to progress though.

   When it comes down to the audio of a SquareSoft game, I expect no less than perfection, or whatever is closest to it. With Kingdom Hearts, I get what I am used to; some of the finest videogame music scores, not to mention some of the finest voice acting around, with the exception of Wakka's ever annoying terrible accent. Thankfully Wakka doesn't play a notable role in Kingdom Hearts, so players do not have to suffer that much listening to Wakka speak.

   Now what makes Kingdom Hearts even better is the fact that the game features a huge Hollywood cast. Haley Joel Osment takes on the role of Sora. While Riku is played by David Gallagher. Kairi is played by Hayden Panettiere. Lance Bass does the voice of Sephiroth (weird, we know). Mandy Moore plays Aerith. Billy Zane does the voice for a mysterious hooded character which you will encounter early on in the game. There are dozens and dozens of notable Disney voice actors, and as far as I could tell all of them are the original voiceovers, as Square claims. The soundtrack is phenomenally done as well and very memorable. All in all, the sound in Kingdom Hearts is some of the best you'll hear all year. A wonderful soundtrack and nearly perfect voice acting has become the standard with SquareSoft.
