I've got a great Sci-Fi idea in the pipeline but I have had trouble choosing the time frame from which it'll take place. I originally wanted to set it in circa 100,000, with the earth swallowed by the sun. But I have won't believe that a technology that primarily features in this story (it actually is part of the MC's persona) would've been created that late in time. Now it'll probably be set circa 3000-7500 with the earth beyond recognition from what it is now. I think that the tech would be created around this point with the way most media (video games, books and filmed media) depicts technology of the time. I don't really want it set pre 3000 but I know 2700 could be realistic. If you are wondering the technology discussed would enable the user to take the virtual form of someone else. Physically creating material, changing voice and giving an advanced database to choose people from. I know, advanced stuff. Other must haves include FTL travel and the formation of a intergalactic government with each planet having a selected representative. There would be a planet dominated by skyscrapers, some even going deep into the surface, called Avalon. This has been functional for decades with the lower levels going into disrepair. Any advice in which era this should be set?
