A big part of New Dublin is the technology. The tech in New Dublin is at a different level than we are now. They’re a few years advanced; see cyberpunk games like GURPS, Shadowrun, D20 Modern for ideas or movies like Minority Report, Paycheck, Blade Runner, Final Cut or the TV show Dark Angel.
Things you won’t see that you might see in one of those movies; flying cars, androids (there’s cybernetics, but no androids), cloning, mutants or psychics (people who think their psychic maybe, but not really psychic). Keep in mind that this is futuristic, but not too futuristic. Think about 25-50 years in our future.
