I usually think that my Canon is probably a bit bigger than it actually is...
And I have levels- not that I really classify them (yet) but that even if I consider something to be 'canon', it's not always terribly relevant.
If someone wrote a short story (or comic (Star Wars Tales, maybe)) with a new scene of Han, Leia, Chewie and C3PO passing time on the Falcon on the way to the Lando system, and I liked it and it didn't contradict anything else I considered canon... I might not throw it out of my "personal canon" but it wouldn't rank very high as far as "importance" or "relevancy".
Even so, here's what I consider canon personnaly like and watch/read/play.
Original Trilogy-
- Star Wars Revisited hits about 10/12 cylinders for me. If I wasn't so lazy/was more talented I'd make my own Revisited Reloaded and be 99% happy.
- Adywan's ESB Theatrical (Until I can see ESB:R)
- ??? Still not sure about a RotJ. I've d/l'ed a couple and checked out a few less.
Books- (I read everything from Splinter of the Minds eye to something around Planet of Twilight. I've read each of the PT novels and 1.2 of the Darth Bane books. I used to consider a lot of more of them canon, but now I guess it would just be:)
- Zahn Trilogy
- Most of Jedi Academy Trilogy
- Children of the Jedi (maybe? I only read this once when it came out, but I recall enjoying it)
- The first several Young Jedi Knights books (again- haven't read in ages, but I recall these being surprisingly good, considering the author (we hates the KJA, we hates THEM!) and the subject matter. But they're far enough removed from the core characters that I don't really care one way or another. See my earlier note on relevancy.)
- Maybe 25% or less of The Courtship of Princess Leia. As if it's a really poorly written tabloid version of it or something.
(Yet to read, but looking forward to them:)
- Hand of Thrawn Duology
- Survivor's Quest
Comics-
- 75% of Dark Empire
- 50% of Dark Empire II
- 10% of Empire's End
- 100% of Tales of the Jedi, Freedon Nadd
- 90% of Dark Lords of the Sith
- 70% of Sith War
- 50% of Golden Age of/Fall of the Sith Empire
- 70% of Redemption
- 99% of Legacy, Legacy War
- 90% of Mara Jade, Union
- ~% of the X-Wing books (I guess)
- 1% of the Star Wars Tales
I didn't completely hate the KotOR books, and I read the whole series. I'm tempted to throw it on this list, but nah... I've only read a little Empire/Rebellion and they've never really felt like must reads to me.
Games- (This is harder. The above are all "story" media, whereas this is something differnent. I really enjoyed the act of playing both Force Unleashed games, but I wouldn't ever consider their stories canon)
- 100% Dark Forces
- 50% Jedi Knight
- 60% Jedi Outcast
I guess the rest either weren't trying to have their own continuity (Battlefront, X-Wing, Super Star Wars, etc...) or had such terrible stories (Rebel Assault, etc...) or had nice stories, but they just don't fit (Force Unleashed).
