That's a matter of opinion.
DH amde some unique comics. Marvel focused on milking the big 3.
Dark Horse plans on doing the exact same thing now with their upcoming new ongoing series simply called "Star Wars."
But one thing to take into consideration is that when Marvel had the license, the big 3 were
the focus as the original trilogy was still being made at the time. It's like blaming DC Comics for milking Kirk, Spock, and McCoy when they had the original Star Trek
license prior to TNG's debut.
