D20 is Wizards of the Coast's Universal role-playing system. They released much of the game material in the form of the Standard Reference Document, and the Open Gaming License. The OGL allows for the creation of material for this D20 meta-system, and has spawned enourmous amounts of material licensed under the OGL.
Alternate d20 Rulesets
Vitality and Wound Points are a somewhat more realistic Hit Point variant originally introduced in the Star Wars d20 RPG.
