Damn man, now you've got me thinking!! Into the brain cauldron...
BTW, I occasionally think about a new version of this game. I wouldn't change it much. I would likely add a stack of poker chips to represent "level" and introduce stunts - which would be sorcerous things you have done in the fiction before and for which you are automatically an expert. The levels would start at 3 and increase by 1, up to a max of 10 or 12. Each level would represent one "hurt" you could take before going out of action (not hit points at all, but rather fictional conditions representing harm).
