RPG : FUDGE system

Yay. Ash pointed this out the other day, the 'open-source' FUDGE roleplaying system. Works how I've dreamt, but these guys had the tenacity to sit down and type it up. Lots of excellent examples; basically an open ended system you can do with what you want. They suggest a method of die rolling that seems ok, but that is about all that is 'concrete' in the system.
I love it, find it here
