Alright, where would you guys prefer I put this? Keep in mind of course that I prefer a LOT of plot with my sexy time, so where this game gets put is just a manifestation of what you guys will want to be POSSIBLE in it.
Light - Seattle's BDSM and other exotic clubs are shuttered, gangers keep it in their pants and romance is alive and well in everyone! SURGE never happened.
B, D/S, M - Seattle's various clubs are all open and the passions are wild, but it's all very romantic. Gangers are still well behaved. SURGE never happened.
NC - Seattle and the world beyond are a dark place. You don't walk The Barrens at night alone and stay away from Bunraku Parlors if you wanna be safe. SURGE never happened.
NC: Exotic - Everything above, but Haley's Comet came and went, twisting a minor subset of people into... weird things. Seattle opens a club for "Changlings".
Extreme - All of the above and so much more. Sadistic corporate goons might 'feed' you to hellhounds or experiment on you in other ways. Bathrooms, Children and such however never appear. Your GM can't write that stuff, so no.
