As an avid Star Wars fan I've played both the original Knights of the Old Republic video games and the more recent MMO Star Wars: The Old Republic. The story that is carried out in the first KotOR game is exceptional and meshes with the story in the KotOR graphic novel in the sense that you see both Revan and Malak during the Mandalorian Wars.
However, my favorite part of the graphic novel is the new story and characters. Zayne Carrick (main protagonist) is a jedi padawan with a "unique" bond to the force. he's extremely lucky and clumsy. Carrick becomes embroiled in a plot concerning the Jedi and the lines between good and bad are instantly blurred. Carrick's unwilling allies make up the team of heroes that every Star Wars story is never without! Every character has a unique skill set and back story that carries throughout the graphic novel. I'm trying not to give too much away, but if you like comics, Star Wars, or even more specifically a fan of the Old Republic Era, this series is a must read!
