The primary reason why I have the Hand of Thrawn duology as my cut-off point. The Galactic Civil War is finally over, Luke and Mara are engaged to be married, and Leia has that sweet ruby lightsaber. The best possible ending to the Expanded Universe, I say.
I prefer to end the Expanded Universe with the NJO series and the end of the Yuuzhan Vong invasion. But if I have to put myself in your place, then, wouldn’t it be better to end the Expanded Universe with the Union comic in which Luke and Mara get officially married and the war is officially over? I think their wedding ceremony could be a nice ending for the universe as well.
The comic came out six months after TPM. I consider everything released on and after May 19, 1999 non-canon. Plus it has Jedi in desert hermit robes.
That’s an automatic disqualification.
