Meta-history and background
In 1996 Imperium Games becomes a subsidiary of Sweetpea Entertainment. Founded in 1994 by Courtney S Solomon and John Benitz, Sweetpea Entertainment is a film production company who negotiated the rights to the Dungeons and Dragons movie from TSR.
It is suspected that the TSR connection is how Sweetpea found out about and acquired Imperium Games.
On March 31 1998, Marc Miller announced on the Traveller Mailing List that Imperium Games would no longer be producing Traveller materials. Sweetpea Entertainment decided to let their Traveller license lapse with the rights reverting back to Marc Miller.
