From publisher blurb: This is a re-edit and compilation of the various core rules companions for the Big Damn Sci-Fi system. Maby of the published core companion documents published to date have been editted into their proper order and priority to create a final set of core rules. Streamlined to jump to warp one, Big Damn Sci-Fi is still a fast and simple science fiction game. Cutting out repetitive statements like, “what is an rpg,” generic science fiction “fluff” and ditching preset races for modular “species traits” Big Damn Sci-Fi leaves you with a flexible universe and roleplaying system. Its not just Big Damn Sci-Fi, it's your Damn Sci-Fi.
