That's totally fake. I saw that, too, and it's obviously fake. Nomura already said it wasn't called "Kingdom Hearts III". And why would it be rated T? This is Disney... -_-;
Dude, it's called strategy. If you actually play the game, you'll see how hard it really is. I may not have played it, but did anyone else who didn't use the strategy win against him yet? He's harder than Sephiroth and THAT's something...
