My wife to be (who beat the game perfect in 40+ hours with no deaths or helping from Mickey) and I were talking when she was playing this game, and since they put live action characters into the game and not the standard cartoon character, their are some huge possiblities for KH3. You could have Sora in the Incredibles, image him with some kind of super power (LOL) or even Toy Story, Shriek, freakin Jumanji, Last Starfighter, ect. This game has still so much potental that they have not really touched on. The adding of a second Keyblade to fight with is indeed a nice addition, but, the only real use for it was to get the growth abilities, and some of the Cup battles. I would have loved to be able to use it with no limitations in a final fight.
The one and only thing that bugged me was some worlds didn't have Sora and party dressed up to blend in. The first game had every world and in it Sora was dressed to fit in like Holloween town, they look like gothic idiots, but in Mulans they werent dressed in the style of clothing, nor where they in Beast's world. What is the point of dressing to blend in some worlds, nd not in others. I understand the underwater, and the lion forms were needed, but come on be consistent.
I would love/hate to see a Siefer & Seporoth tag team fight against Sora and maybe Riku. That would be a bitch to pass. Maybe after have a rescue from the battle by Cloud and Leon. That would kickass.
As to selling so many copies in so many days, like stated by me before, wait till the new Final Fantasy comes out. The online one doesnt count since not everyone who had/has a PS2 has the ability to play it online. Playing KH2, I have been jonesing like a crackhead for a new Final Fantasy game.
On a sidenote, I popped in KH1 and damn it's funny how deep his voice got.
