I will never give my old consoles away, because it's my childhood and sometimes the new consoles can't play the old games.
Wii can't play N64 games, Nintendo 3DS can't play GBA (and GBC) games and Nintendo DS can't play GBC, but GBA games... and so on ^^
I would choose the proud mode, but not for "get the secret ending faster", more for: "because standard is... too easy for me?"
And I can search all items and the other things on proud of course, too. =)
I think Sora is 16, too.
Because Ansem the Wise said to Aqua in the Secret Ending of BBS: "It's one year, I think..."
So Sora must be 16 (and Riku 17)
In 3D are looking Sora and Riku younger, because they are "only" dreaming ^^
But: Aren't the clothes from KH2 became meanwhile smaller?
They can put in it "The lion King II", "Aristo Cats", "Adventures of the Gummi Bears" and probably "Monster Inc." (all mönsters be shocked)
Yeah, this would be... funny ^^
