As players of the 2300AD RPG know, the game universe is the same as that of Twilight: 2000, only 300 years in the future.
The intervening 300 years was developed by the staff of GDW in 1985-86 through a macro-political game ("The Game") where players each took the role of several countries, playing them in decade-long turns.
The rules to The Game can be found on the web, but whatever happened to the map
in the years since then?
I created The Game
page to answer that question with exclusive recollections and photos from GDW alumnus Dave Nilsen.
