Galactic Warzone
From Break Into Chat - BBS wiki
Galactic Warzone is a multiplayer space trading strategy door game for bulletin board systems modeled after TradeWars.
Galactic Warzone was developed by Scott Baker, beginning in the late 1980s while he was in high school. The final version, v7.6, was released in August 1990. Baker has said he didn't do a good job marketing the game, but it was popular enough that he received a few thousand dollars in donations.
