"There's no question that the original Kingdom Hearts was a tremendous success and captured the hearts of countless gamers. Combining the charming and often nostalgic worlds of Disney with the exciting, intricate style of Square Enix, Kingdom Hearts is still remembered as one of the best PS2 games around. However, many fans of the franchise were quite bewildered upon booting up the proper sequel because so much had changed from the first game and a good chunk of the story between the two titles was told in the GBA game Kingdom Hearts: Chain of Memories. Gamers that didn't have access to a GBA missed out on a wealth of important information that wasn't entirely covered in Kingdom Hearts II."
