I just hope it could come it out in Australia, and i have the kh2 officila guide, so i hope some stuff is transferable, but then again if i can't find stuff cos the guide isn't compatable, ill just go on the net and look up stuff.
some easier stuff: Each time you beat a orgg xiii data copy, u get a stat boost item
roxas's victory keyblade makes it quicker to get final form
there are nine drive guages, so if ur wanting to level up wisdom or valor, u can dirve 3 times before u have to use the save point/world map or cerberus cup drive regenerators
I might have read somewhere that a new addition is to synthesize draw and lucky rings, so itme hunting would be easy as pie.
some hard stuff:
Cavern of remeberance
Critical mode
Org XIII data battles
Roxas story mode battle
Terra Battle
Crown gathering
Mushroom XIII battles
Overall i would not care, i see it as a special edition of kh2, and thus it should be a better experience
