Rishonomic was a short-lived EmailNomic in 1997 featuring a large helping of silliness. It died perhaps the most dramatic death of any nomic, when a TerribleProposal was adopted, along the lines of
Upon the adoption of this proposal, the ruleset is amended by replacing all numbers with the phrase "A Suffusion of Yellow".
Attempts were made to continue with the gravely wounded ruleset, but ultimately it was abandoned as unplayable. Many of the same players continued with NewRishonomic, which started with several of the rules that had been devised in Rishonomic.
In May 1997 Rishonomic came under sneak attack by infiltrators from Agora, in the RishoAgoraWar. The motivation for the invasion was a rule that Rishonomic had enacted early on which insulted Agorans. The invasion failed when an Agoran traitor tipped off the Risho natives. Rishonomic's death was blamed by some on the Agoran conspiracy, although the fatal proposal actually came from a native Rishon. Ironically, if the Agorans had succeeded in planting the rule they intended to in Rishonomic's ruleset, it would have provided a way to restore the ruleset to a playable state.
