OSR Commentary - Going 2d6 Fantasy Dark Ages In Your 2d6 Old School Science Fiction campaigns!

 So I've been considering doing a failed colony world in my Stars Without Numbers rpg game/Cepheus Engine rpg campaigns  & yes, Other Dust is an option. But the players actually know that resource front to back. So I drifted back to Michael Brown's Afterday &  Cepheus Atom. This blog post is going to pick right up from this one here. 

Afterday presents quite a few resources that line up with a limited post apocalyptic world. And its great for Cepheus Engine powered campagins. Cepheus Atom brings the 2d6 gonzo to the table in spades with its mutations, & other post apocalyptic resources. 
The wastelands of our colony world may have access to  entropic  weaponry and so this brings the dangers of those reality warping weapons to the table. It also explains the mutations and mutant monsters. 
Here we're thinking of going full on Cepheus Atom mode, adding in Atomic Age Barbarians, tribes of mutants, etc. 

The wastelands may have magick but I'm not sure about adding a full range of  the Sword of Cepheus fantasy rpg, here. But it might be an option here as a fantasy Dark Ages world existing in the same sector as a failed entropic wasteland world tells volumes. 

I'm thinking of forgoing the Barbaric Rpg route & going on full Sword of Cepheus because the presence of high magick adds a lot more to such a strange twist or two to the campagin mix. Could all of this be added into an Independence Game Space Western campaign?! Think 70's Dallas mixed with Game of Thrones level politic moves coupled with family politics.
