The DUDE Game System

Introduction
Diceless:
DUDE uses regular playing cards for task resolution instead of the dice common in other games, and by holding different-sized hands, each player has more or less control over the results of their actions, rather than being at the mercy of blind chance.
Universal:
DUDE can theoretically represent any genre. However, it does work best at fast action-adventure stories or freeform dramatic gaming; complex mechanical simulation of a world is not within DUDE's abilities.
Determination:
DUDE uses a unified task system to handle all actions. And unlike other (overly-complex) games, it doesn't waste your time trying to remember which stat affects a task.
Engine:
DUDE is only the basic mechanics of an RPG - you will need to acquire or write a setting book. See The Alan Smithee Project for an example of what needs to be developed in such a book.
