Since the D23 2015 Expo is around the corner, showing off additional info & more for Kingdom Hearts III, I had a deep thought into whether KH3 requires Marvel & Star Wars worlds or not. So, heres my take: Kingdom Hearts' themes has always been about friendship, light & dark and the heart but even though Star Wars occupies one, maybe even two of the themes mentioned earlier, how it's conveyed is different to what Kingdom Hearts does with the themes. Almost too mature & their universe and lore is just too massive to tie it into an already big collaboration between Disney original content & Final Fantasy. For Marvel, I just see the implementation as a service to fans and I feel it isn't a necessary boon for Kingdom Hearts. Like with Star Wars, their universe & lore is big enough to be it's own thing. So I feel that neither of those worlds should be in Kingdom Hearts. However, if a Star Wars world were to happen (by the looks of things, maybe so), then it just has prove it. I can't see any other way for a Marvel world to convince me it will fit into Kingdom Hearts III. What do you think?
