Sometimes I wonder if I am too obsessed...
... and then I come across something like this.
The level of detail and completeness of analysis on this topic is amazing. Would have thought there was an official Lucasfilm database of the Star Wars universe, where each entry is coded with a level of canon-ness? (Get the complete details.)
Oh, and of course Wikipedia chimes in on the topic as well.
I am not an avid consumer of EU-stuff, so I guess I am mostly concerned with "G-Canon."
Though I found it wonderfully precise that there is a category for instances of Star Wars material that use canonical facts, but whose storyline is not canon. (For example: In a Star Wars video game, the characters and their attributes are canon, but what happens when you actually play the game is not canon.) So I guess when my Lego Obi-Wan kept dying over and over on Mustafar, that didn't affect the outcome of Revenge of the Sith.
