Page "Expedition to the Barrier Peaks" Paragraph 7

While D & D is a fantasy roleplaying game, Expedition to the Barrier Peaks introduces science fiction elements into the game.

Work on the adventure began in 1976, when TSR was considering publishing a science fantasy role playing game.

James M. Ward had shown them his rough notes on Metamorphosis Alpha.

Gary Gygax thought it would be a good idea to introduce science fiction / science fantasy concepts to D & D players through the use of a tournament scenario at the 1976 Origins II gaming convention in Baltimore, Maryland.

Gygax started with his old Greyhawk Castle campaign material and added a spaceship, which Rob Kuntz helped him populate with monsters.

Kuntz is further credited for " inspiration " for the module ; his " Machine Level " having been incorporated into Greyhawk Castle and Tim Kask having played in a D & D game with science fantasy content run by Kuntz at GenCon VII in 1974.
