The guide is written to help both the player with enthusiastic opponents but
also to support the solo player as well. My hope is that it will help you
build science fiction campaigns that let you use comparatively small forces,
but in a realistic manner. In this universe you're not a major player, in
fact you're probably not even a major nuisance. You're just a jobbing
merchant, trading your way around the sector, living on your wits and
turning an honest credit whenever the opportunity presents itself.
Although written with Hell by Starlight rules in mind, you should be able to
use other rule systems. 
I confess that I've always felt that done properly, a campaign can provide
far more interesting and unexpected games than just fighting 'one off
battles.' Over the years I've had a lot of fun fighting skirmishes that
nobody in their right mind would create from scratch. So with this guide
I've tried to help you create a coherent background that hangs together for
you. I hope I've managed to balance book keeping with fun, because frankly
if you're not enjoying it, something has gone wrong, no matter how
'realistic' things are.
