Aye. The Dream Project ending especially makes it quite clear that there was, in fact, a new game plus feature in the Japanese version, since most of those team members can't speak a word of English and would not have put such a thing together just for North America, ESPECIALLY back in the SNES era. It's difficult to get Square to release such neat stuff even today, hence the still on-going hope that KH II: Final Mix+ will be released here.
