Regarding Darth Maul, anyone who remembers as far back as 10+ years is at least familiar with the cancelled game about him.
It was supposed to be set around the Clone Wars after he somehow returned, but then, one day, George comes by to check on progress. He notices a figure of EU character Darth Talon and assumes she is meant to be Maul's apprentice/sister in this new game despite the character existing 100+ years later (because, remember, George never gave a flying fuck about the EU). Even after the team sets him straight, he insists they find a way to work her into the game by making this Maul a clone of the original.
THAT is most likely where that concept piece of Maul and Talon came from, and just like Gary Kurtz's alleged original idea for RotJ, fans dissatisfied with the ST latched onto it without a second thought.
