A role-playing game system for historical and fantasy role-playing; one of the first RPGs to be released under an open source (or open gaming) license.
The DR rules system is intended to be generic and does not describe the kind of world (or "campaign setting") to which they apply. The system can be used in a variety of RPG settings by excluding or modifying certain rules. For a historical setting, players simply disregard the priestcraft and witchcraft rules.
THE SIX ATTRIBUTES
Every character in the DR system possesses six Attributes that define his or her basic qualities. They are: Vigour, Agility, Stamina, Intuition, Intellect, and Luck.For ordinary humanoids, these Attributes are measured on a scale that tends to range from 1 to 4. For non-humanoid creatures, the scale can be much larger: from 0 to 12 or even beyond. These measurements are called Attribute stats. Players determine their characters’ Attribute stats when they create their characters. A character’s Attribute stat never changes: it cannot be raised or lowered.
