Combine Gamma World and D&D for example?
I was talking about the old school games with a couple non-gaming friends and I showed them the cover of Mutant Future and they were intrigued.
Subjects swung around the terms they knew like D&D.
Reminded me of a game I ran in the early 1980's...The spaceship Warden crashes down in Middle Earth...Metamorphosis Alpha and D&D.
We basically used the D&D books with conversions to include the creatures and technology of the spaceship. The setting was 100ys later...a toxic jungle has grown over the spaceship...vast layers of dark jungle.
Characters were from the local villages around the toxic jungle...minor mutations were common (1 or 2 mutations and no defects for player characters)...elves shunned the toxic jungle, so no elves or half elves...dwarves have dug tunnels through the mountain on the other side of the spaceship where it came to a final stop, but have blocked them off due to the toxic jungle roots and more breaking through...halflings, humans, dwarves, half orcs were the player character types...wildly mutated orcs were quite common, raiding the villages and retreating back to the jungles...
Easy enough to create a game scenario along these lines for Mutant Future...change the names...
It was fun then...surely has potential today
