The european Version is the same like the U.S. as far as I know.
(I've got the german Version) Axel's Death is censored, I'm not sure 'bout Xiggies Weapons...
And I don't care about Will...
If there's ever a release outside Japan, than I want the japanese Version.
(In Germany they're too lazy to take the original version and translate that and always take the US Versions)
And if there's something that's to bad, they change that. Just like Roxas said to Riku:"Shut up!"
In german it's something like:" How should I know?" (when he askes him why he has the keyblade)
Well...we've got KH1 and KH2 with a rating at 6 years not 12.
