Unlike base Dungeons & Dragons (3.5 Edition), Living Greyhawk (LG) used a Point Based (allocate points to get skills, powers, etc) method to generate ability scores and fixed hit points and starting gold. This was to facilitate convention and worldwide play among a vast player network.
The campaign used dungeons-dragons-3rd-edition rules till 1st of March 2005 - all characters played from that day on needed to be dungeons&dragons 3.5 compliant.
The administration of the campaign and the player's characters was done by a team of volunteers for each region - called Triad - and a group of RPGA members "The Circle of Six".
Most of the scenarios for the campaign are written by players within the campaign. The scenarios and the outcome of a scenario - success or failure of a group of characters - may have direct impact on the political situation in the campaign setting.
The campaing starts with the given setting of the World of Greyhawk presented in various sourcebooks as it is in 590 CY. As the players/writers/triads develop the situation over the run of the campaign, the whole campaign can be seen as a special form of fan-fiction. Most adventures, regional gazetteers and background material written during the run of the campaign is considered non-canonical.
