NomicWorld was a MUD (Multi-User Dungeon) run by GeoffWong? and SteveGardner at Monash University, in Australia. Its sole purpose was to run an extended game of Nomic. In its heyday, NW had over thirty players, from places all around the world, making it the largest (known) game of Nomic in the world up to that time! (This has since been superseded by PerlNomic, whose 4th incarnation, after a healthy slashdotting, boasted 81 members at the end, and a peak active membership of 42.)
Nomic world lasted for about 9 months, before the wizards were forced to shut it down due to system problems and lack of time to administer it. In that time, several hundred rules were made, and multiple scams pulled off (with various degrees of success.)
To find out more about NomicWorld, read SteveGardner's excellent game summaries, available from the NomicFtpRepository.
- I consulted the 'framers' of this game and suggested an innovation to the initial set of rules which (I believe) they adopted. Instead of having players propose rules in serial, they should do so in parallel, and then occasionally vote on some of the accumulated proposals. That would not only permit a much larger number of players to participate, but it would simulate a legislative body better than the original rule set. -- 'PeterSuber'
The initial rules from NomicWorld are available for FTP from the NomicFtpRepository:

When Nomic World died, some refugees from it established Agora Nomic, a very long-lived email-based nomic.
