How much do the KOTOR comics and tie-in novels pull things from the kotor games?
The novels "Deception" & "Fatal Alliance" cover events that impact the lives of important NPCs from SWTOR on the timeline shortly before the game begins. While they aren't terrible, they are cotton candy for the mind of the sort typical a Star Trek or Dungeons&Dragon tie-in novel. I enjoyed them, but my expectations were spectacularly low. YMMV.
The KOTOR comics are the adventures of "failed" Jedi Padawan Zayne Carrick and his friends. They take place in the time period immediately before the KOTOR game, and the characters occasionally bump into characters from the KOTOR game. Alek Squinquargesimus who later becomes Darth Malak, the main bad guy in KOTOR, plays a recurring role as an ally/good guy, as does Carth Onassi, another major KOTOR NPC. Back issues are available in graphic novel format.
I love the comics- they have just the right blend of science fiction, dramatic adventure, comic-relief, KOTOR nostalgia and overall StarWars-i-ness. The first five volumes, which Zayne spends trying to prove his innocence of murder and bringing the guilty parties to justice, probably contains one of the best EU story arcs out there, maybe the best after KOTOR. "Wrongly accused of murder" probably sounds like the setup for a gritty anti-hero, but Carrick is more of a nice-guy comic-hero. It still seems to work somehow. I can't recommend them enough for a fan of Star Wars, KOTOR or comics generally.
