And, unfortunately, it is not only George Lucas who we're talking about here. Many others, authors, game designers, etc. alike, who worked or are working on Star Wars projects at the moment, have no clue as to what they created or are creating, and only care for the game, the book or the their characters to be good (in the character's case, powerful) even going as far as sometimes contradicting higher authority or making a character more powerful than he/she is supposed to be. These people, who cannot actually see the Star Wars Universe with a deep, intelligent view, are the ones ruining it, as a whole.
Great examples for this would be people such as Karen Traviss or Haden Blackman, who have absolutely no clue about what they are writing or making, and who simply make their characters immensely more powerful than what they should actually be (i.e. Boba Fett & Starkiller).
