While it's true that the chicken-comp has the word "comp" right in the
title, this is not so much a competition as it is an exhibition. There
is no judging, no averaging of scores, none of that. So why "chicken-
comp"? Well, for one, as we all learned at the ifMUD comedy panel,
Alliteration Is Funny. (We'll ignore the fact that "tš" and "k" are
different phonemes.) But more to the point, I have no doubt that the
games below will generate comparison, discussion of which ones r001 and
which suck, and to that extent, the "comp" part is implicit in any event.
Okay, I'll shut up now.
