Hmmm. I have been thinking of doing something more or less "post"-civilization although I'd like to use it more as an excuse to put some exotic power centers amidst the wreckage. I was thinking something more like a competition/ maze mainly involving competing or pursued Asian fems, though
It could be private entertainment for the powerful, a twist on simple survival for a recently devastated population, more clannish like Princess Bride, a futuristic game show with mean twists, or a combination vaguely like Battle Royale (more combat and sexual tension) or Avalon (more exploration and surreal paranoia, I rather like that one).
But it's been ages since I've run anything, I would want the characters to really fit whichever theme, and I don't tend to focus on the site more than a few times a week. I wouldn't want to run anything too fast-paced, heavily system mechanics, or highly graphic (although I do like some bdsm, lots of fetish attire, and less-consensual, plus sometimes dice-inspired chords).
I'll sit back for a moment and see if those general thoughts strike any chords with this whole Fallout business, or no.
