Somewhat interested in the RP, but Isotope's assertion of the West's stoical resistance to technological and societal stagnation and regression doesn't add up with the RP's initial premise. Patently, history tells us that the West is worthy of respect and formal recognition for its technical and martial prowess, but I sincerely believe that he's severely overestimating its capabilities.
When you've lost 90 percent of the world's total population within a very short time span to ICBMs, biological agents and a teeming demographic of bestial mutant lifeforms, you're looking at the immediate destruction and gradual degradation of entire ethnic groups, racial groups and religious groups of Earth.
This event makes the cumulative effects of every single natural disaster and war in human history look like petty child's play in comparison. With 770 million persons remaining in the world, humanity just got bumped back down to (roughly) 1750 population levels; infighting amongst human populations, mutant incursions and the very real possibility of pathogens springing up out of nowhere aren't doing the species any favors, either.
EDIT: Anyway, I might play some remnant of the US.
