Kingdom Hearts Re: Chain of Memories is a playstation 2 remake of the 2004 Game Boy Advance game , and follows the story of Sora, Riku, and their Square and Disney character companions, in the time between the events of the PS2's original Kingdom Hearts and Kingdom Hearts II. As in the GBA original, the play of the game is driven by memory-empowered cards that the characters collect in their travels. The various cards can be used to perform special moves in combat or to create rooms containing treasure, enemies, or save points. Display of card information is more detailed and accessible in the PS2 version of the game, and managing a deck of cards is easier with a Dual Shock 2 controller. Released well past the console's prime, the game makes use of many well-honed graphical and presentational techniques to enliven the Chain of Memories story from a fresh perspective. Characters are voiced by the actors who performed them in the original PS2 game and its sequel, including Haley Joel Osment as Sora and David Gallagher as Riku.
