I personally think it would be awesome to have dragons in a non-medieval setting.
Dystopia is the kind of science fiction that portrays a world in which everything is kind of broken, usually wrapped up in the idea of the perfect society. Corruption, authoritarianism and control are staples of this genre. Examples of dystopic societies include Aldous Huxley's Brave New World, Ray Bradbury's Farenheit 451 and George Orwell's 1984.
The way the poll is looking right now, I have this mental image of a medieval setting, but with futuristic technology (maybe tesla-esque wireless electricity) and an evil, authoritarian empire using telepathic mages to control people's thoughts and actions.
