This is maybe a little over-ambitious as I've only GM'd one game and it was using the Age of Rebellion beginner's set, but to be honest I have been so, so very excited about starting this game and leading a group of friends through their own Star Wars story that I can't help myself.
I came up first with a generic outline of the beginning of a story I want to tell -- I have a villain, I have my heroes, I have an ultimate goal for them to build up to, and tried to throw in a few twists and turns along the way. But as I've been writing the adventure, I've come up with some new ideas, some other characters, and I'm hoping that I'm capturing the feel of the beginning of a Star Wars film for this first adventure. I'm planning on turning it into my own campaign, but I'm trying not to get ahead of myself, either -- at the end of this adventure, my players are going to be able to make a really big choice for themselves, which will influence how the rest of the campaign will go.
Anyway, I'm really only posting because I'm excited to be a part of this now!
