Core Fuzion is the core of a game system which allows YOU to build your own house rules. With its adaptable, flexible mix-n-match systems, Fuzion allows you to mix settings, bend genres, even shift between campaigns without losing a beat or just tailor the genre you love to fit your interests. All in a book you can read in an evening. Tell us you never wanted to put laser weapons in your fantasy campaign! A very good copy of the first edition of this multi-genre roleplaying tool.
