Weren't you asking for the difference between Kingdom Hearts Final Mix and Kingdom Hearts 2 Final Mix +? Countless changes in KH2FM+. The list goes on. I'd be angry if you were asking for those, lol. And you don't want to see me when I'm angry. Basically, KH2FM+ has KH2FM, a remake of KH2 with more features. The plus is for Re: Chain of Memories, a remake of CoM for the PS2. KHFM is a remake of Kingdom Hearts.
