A Variation of Fudge From the introduction: This is just my variation of the standard Fudge rules[...]Fudge offers many possibilities, and often provides several alternative methods of dealing with various aspects of role-playing. Genre Clash uses nothing that is not already included in the basic Fudge rules, but this document is provided to detail exactly which of the Fudge options and rules will be used. Having your own copy of Fudge might be nice, but is not at all required to participate in Genre Clash.
