I agree wholeheartedly with IrishLuck though i would say nothing past 1995. Except for the bantam novels and the dark horse comics.
1996 was shadows of the empire, now i don't entirely hate shadoes but characters like Xizor and Dash Rendar aka cheap Han Solo knockoff were not needed.
1997 was the year that will live in infamy the year that buried the originals forever, and allowed these bastard creations called special editions to take their place.
1999 Jar Jar and prequels premiere nuff said. Also Chewie dies in Vector Prime and the New Jedi crap. i mean order novels are released.
2006 non anamorphic gout from 1993 laserdisc released as bonus discs.
