Of course, I am making notes for myself as well. Ever since Glow I have been playing around with the same sort of vein of RPG.with notes on the Earth about a million and half years in the future. Now while this is not after the red dwarfing of our star and definitely no where near the heat death of our universe, it's still a pretty far out place to be. Take a look at the life on Earth 1.5 million years ago and compare it to now. From woolly mammoths and more than few hominids living around each other in terms of time and space, to one human species and pets leaving plastic covered tech for an epoch to come. So what does my FFFFRP setting look like?
Well there are the Nimby. The perfection of humanoids able to take and hold the lands not radioactive or chemically tainted from ages gone by. We'd recognize ourselves somewhat in the four-toed Bagger, that pretty much populate where humans once did in larger numbers. Often the Bag, a diminutive of Bagger, are subservient to Nimby families. And then there are the Imby, small and nimble and evolved to "smell" radiation and poison so are somewhat able to survive in the wastelands that pock various spots on this new Earth.

After my own notes on this for gaming, I've not used it as such. Instead I have been writing fiction in this epoch of weirdness. We'll see what comes of it.
