I thought of another mechanic I really like, this morning- from the Doctor Who Adventures in Time and Space rpg, like most games there is a list of Attributes (Awareness, Coordination, Ingenuity, Presence, Resolve, and Strength) range from 1 through 5 human max and 6 supernatural, 3 being human average. However unlike most games there are no hit points. The damage system takes temporary points from the actual Attributes depending on what the attack was. Physical would naturally take from Strength or Coordination or both, a head injury might reduce Presence or Resolve. I hadn't seen this in any game before and thought it was brilliant.
