I'm a fan of the zombie version, which is a hoot.
I felt it failed to live up to the promise of its concept.
In other news, all these numbered rules made me think of Rule #34. I lost.
I published Nomic in 1982, about seven years before my sabbatical in Hofstadter's lab. But I published it in Hofstadter's column in Scientific American. We got to know one another through Nomic, and it led to the sabbatical at his lab, not the other way around.
There's nothing confidential in this; please feel free to post it if you think it would interest others.
Another similar game which is just as good is Bartok (or Bartog or Warthog, depending on who you ask). Similar to Uno, but when you win a round, you get to make a new rule which applies to every future round. Best played with drunken Mathematicians/CS types.
Finally, if you want to be really scared, there's PerlNomic, in which rule changes are actually diffs applied to the voting code: http://www.nomic.net/~nomicwiki/index.php/PerlNomic
For those about to try it in school: You should probably add a fixed rule about not ending class prematurely and going outside to play (my students needed a rather long time to come up with this loop hole). But it was an interesting hour which served as an introduction to the 10 commandments.
