9. Aurebesh
The Star Wars universe is a vast place. With over thirty years of almost endless tie-in material its become one of the most developed fictional worlds, trumping Narnia, Middle-Earth and Oz with ease. And, as any fantasy universe will have when it gains a strong enough following, it's developed its own language. Not quite as in depth as Klingon (for which an edition of the Bible exists) or Elvish (which Tolkien had much more love for than the stories he created), Aurebesh is still a mainstay of the world. The written form of Basic (the in-world name for English), its an alphabet similar, but not quite, to our own that appears all over the games, TV shows and, yes, films. Originally just made up symbols intended to look spacey, it developed meaning (allowing audiences to see what exactly R2s saying to his pilots when in space). The language didn't exist until after the first film and thus our traditional, English characters were used. When it came to the DVD, Lucas decided to rectify that and digitally changed the words, most notably with Power on the tractor beam controls, to their Aurebesh equivalents. A small, but effective change.
