Triplanetary

Triplanetary was a science fiction board wargame published by Game Designers' Workshop in 1973. It was a simulation of space combat within the solar system in the early 21st Century. The game was designed by Marc W. Miller as part of a series to be named "The Stars! The Stars!". A second edition of the game was issued in 1981. In 1989, Steve Jackson acquired the rights to the game, with ambitions to release a new version of the game in 1991. However, although a draft version was created, a new edition was never released.
