Hands down not worth buying unless you really, really, REALLY liked the data organisation boss fights from kh2Remix. Other than the data true organisation boss fights, Re:Mind only adds the ability to walk around Scala ad Caelum - AFTER you've rewatched the last 3 hours of the base game and refought a handful of the last bosses. The dlc is lazy at best and insulting at worst, there are no significant story details added or revealed and nothing much else to make up for it. If I could get a refund, I would.
