Everybody familiar with the d20 system knows that it is a fantastic system for representing fantastic feats of fantasy... but fails utterly when used to represent more real-world situations or trying to make new materials for use in the system. The Universal Decay variation fixes this, focusing on both extreme realism and ultimate in-game mutability. Using the Universal Decay system even the best-trained warriors have to be careful when going sword-to-sword against their foes, and you can have just as much fun developing new technowidgets as you can defeating armies. The rules are flexible enough to not only encompass any conceivable situation, but modular enough so that players only deal with complexities they feel comfortable with.
