Also, a hindrance could be that, since the first "story" I was going to write was about your Shadowrun campaign, since none of you guys know what the others do or have done, writing what I originally intended to write could give away information that the others aren't supposed to know. This means that I'll either have to modify the story to a universe in which you aren't all mortal enemies, or wait until you guys do that without any GM intervention.
It's a choice I leave up to you...
