Original Dungeons & Dragons Blackmoor, Gamma World First Edition & the Temple of the Frog

Yesterday was an extremely busy day but there was time enough to look deeper into 1975's Blackmoor supplement. While product designation TSR 2004 is usually known for temple of the Frog. Actually original Dungeons & Dragon Blackmoor actually has several other uses. 
Deep within Blackmoor according to the wiki entry is an entire section on underwater adventures;"The supplement introduced rules for underwater adventures, such as rules and guidelines for swimming, equipment weight restrictions when fighting underwater, and the effects of underwater combat on weapons and spells. Blackmoor also includes numerous new water-dwelling monsters and equipment useful for underwater adventures. A number of these underwater monsters and magic items were the creations of Steve Marsh" 
And while this does complement Blackmoor's Temple of the Frog it also comes in incredibly handy for those who want to run first edition Gamma World's GW1 Legion of Gold's underwater adventure section on the Legion itself. 

Blackmoor also hits the high notes for Gamma World first edition by providing the rules framework for further underworld adventures. This is a fact that has not been lost upon me. 

Speaking with my players yesterday there was talk about the fact that Temple of the Frog itself could be switched over to Gamma Terra & no one would be the wiser. The Froggies, the advanced technologies, and more are all reflective of the dangers present within the radioactive wasteslands of Gamma World. And what about an NPC assassin straight out of the bowels of Blackmoor that could well be a Red Death operative or agent. Stepthen The Rock could easily be slipped into Gamma Terra and few if anyone would be the wiser that the Temple of the Frog fits easily into the wastelands of Gamma World.
