By far my favorite series along side the Mario series. The story is just simply incredible, and the game is fun to boot. Ever since its realease back in 2001 I fell in love with it. I first heard about it on T.V, and I was so excited to have a video game where you can play through Disney movies as a completely new different character and have him change the Disney movies around. The funny thing is when I first heard about it I misread the title and thought it was called, "The Kingdom of Hearts." XD All of the games were awesome, albeit I didn't like the battle system for Chain of Memories that well, but the story was still awesome! The new KH game will be announced at the Tokyo Game Show, but it will not be Kingdom Hearts III, but rather a game that chronicles the other characters from the series such as Roxas and the three knights from the ending. I own 1, 2, COM, and the first Final Mix.
Yeah, about the whole deal with Mario in the game, that was an April fools joke for a game called "Mushroom Kingdom Hearts." If that was an actually game I think I'd have a heart attack. XD However, I actually wrote a story that retells the story of KH with Nintendo characters instead of Disney characters. KH will always be the best!
