What JK calls Persuasion is actually a completely new Frce Power that I call "Limited Invisibility."
Limited because it's a mental effect and it wouldn't work on droids or cameras (unlike in the game).
What Ben use in ANH is "Affect Mind" (to con the troopers on Mos Eisley) and "Illusion" (to distract the two stormies on the DS --in this case it was an auditory illusion, but an illusion nonetheless).
There are several hundred force powers that we don't see in the movies/games, and even the books; they're designed for the RPG.
And that's not even counting Allyan Magic (from the Witches of Dathomir), Ta-ree Magic, Revwien Tyia, Aing-Tii abilities, Sith alchemy, and my personal favourite: Ewok Magic.
