Then you are seriously missing out on like 85% of the story. They are not just spin-offs, especially Birth by Sleep.

You ask for Marvel and SW? and you didn’t even know that Stich’s world was in BBS , claim to be a KH fan but only played the 2 who were released on PS2? You, sir, are what is called : an old fashioned American Douchebag.

Really? Well, that means you missed out on some of the main story and some background story. Not to mention that Birth by Sleep and Dream Drop Distance are both fantastic KH games.
