The Great Galactic Conflict, or GGC for short, was a turn based Massively Multiplayer Online Game (MMOG) which was available in Australia around 1985.
The game was accessed through a text based dialup service from Telecom Australia (later Telstra Australia) known as Viatel.
Briefly, the game mechanic required players to enter their moves during a one-week period. Once a week the game engine would process all entered moves and compute a result which became the basis for the following week's moves. GGC moves were heavily influenced by negotiation between players which formed a significant portion of the game play. In 1988 the winner of the game was eligible to receive a prize of $2500.
The game was written by Ian Davies for Mircrotex 666 from 1983 to 1984.
