I've only finished reading through their version of the Phantom Menace (called The Phantasmal Malevolence). They've been putting out strips since 2007 and only recently started on the new trilogy, so this is still a work in progress. However, my one of my favorite things about the series is that they also include a bit of introspection about each strip and role-playing in general, giving various levels of guidance about how games should or should not be run and how gamers should and should not play them.
I know. I'm geeking out a bit here, and I've lost most of you. Let's just say that this was another perfect combination of things that I love (comics, Star Wars, and role-playing) that I never knew I was missing. If any of that sounds interesting (or amazing) to you, you should start here and enjoy.
It's also really made me want to play some D&D again.
