Played in AckaNomic under the name "red barn" some years ago. Played briefly in Rishonomic and New Rishonnomic (the one which had two 'n's in its name, or was it one?). Annoyed InterNomic by creating "games" with the same names as its members.
Started a doomed game called AutoNomic?, which had the premise that every player could have total authority over an alternate ruleset. The game was fun until the players realized we were never going to make progress; there was a later attempt to revive it (though nobody informed me, sigh) which failed similarly. The best part of this one was the name.
Played in EcoNomic?, don't remember very much about it.
Currently involved in FourPlay?, a four-player chess nomic heavily inspired by Acka's old Party Chess. It's moving... but... very... slowly.
I wonder whether people view nomic as something they want to have a lasting involvement in, or just a phase? The height of nomic activity to date appears to have been around '97. Those with thoughts should feel free to share them in this space.
