The most fitting starting place I can find for this review is the sound. When questioning just how much production value when into this game, you need not look any further than the cast list. When a game has enough draw to it that it can score voice talent like Haley Joel Osment, Sean Astin, Billy Zane, David Boreanaz, and Mandy Moore; voices from the original movies like Scott Weinger, James Woods, Jodi Benson, and Gilbert Godfried, you know you're in for a treat. The voice work is miles beyond anything that has appeared in a video game. Even some of the vocal mismatches such as Lance Bass as Sephiroth and the 'filler' voices sound great.
When it comes to music, let me get one thing out of the way right off the bat. Although this is a Disney production, at no time do any of the game's characters break out in a song and dance number. On that note, the soundtrack is exactly what you would expect from Square. From Utada Hikaru's theme song 'Simple and Clean' to the simplest of victory tunes, everything is fantastic. Disney fans will get a kick out of hearing new versions of old Disney favorites like 'Under the Sea' and 'The Mickey Mouse Club March'.
Graphically, Kingdom Hearts is just as breathtaking. Seeing how Square was able to blend both the Disney and Square characters and worlds is really something to see. Just trying to pick out a favorite level was a real chore. Every level in the game stays very true to the movies - even down to the smallest details. Some Disney purists are sure to point out some minor inconsistencies, but I am convinced those are people you just can't please. The character animation is some of the best I've seen in a game, especially Donald and Goofy. Whereas most characters have a 'computer' like movement, the characters move like they were in a Disney animated feature. If the overall presentation isn't enough to get excited, the visual in-jokes, such as the Fantasia mops cleaning Mickey's castle or the Cactaur Gummi Ship design, are sure to please both Disney and Square fans.
