What cool plausible science fiction stuff do you think we will be able to buy in about 200 years or so? I'm working on my roleplaying game and got stuck when I came to this part. I'm thinking things like bioscanners, white noise-makers, pens that digitally save a copy of what you're writing, nano bandages, and more. I don't have any scifi RPGs in my collections, so I don't have very much to find inspiration from at the moment. You have any ideas?
