Mike Tresca talks about Sci Fi/D&D and Blackmoor at ENWorld

[Havard]

(3) I noticed a mention of Gamma World in the article, but I didn't see one about Metamorphosis Alpha (which came first). MA was also a hybrid of a fantasy and scifi campaign, what with the tribes of mutants wandering around with spears and blasters.

Weren't both Gamma World and Barrier Peaks attributed to being inspired by Metamorposis Alpha?

Barrier Peaks is obviously also a Blackmoor inspired product, but that was not the time for TSR to give any credit to Dave Arneson...
