Oh by the way I read one of your posts, saying you look at KH as one game. I can understand that. You play BbS first. Then KH1. Like when Sora 'kills' himself in KH1, the screen goes black and Days begins, and then over the 7 days you beat KH1, and then start Days, and then Marluxia, Larxene, Axel, Lexaeus, Zexion, and Vexen go to Castle Oblivion and you start playing it, and then you don't start Days again until you beat Re:CoM. Then once you beat Days you start KH2 obviously, beat that, and then start Re:coded, and if 3D takes place after Re:coded you play that.
