-Under Heaven is the default setting of Game in the Brain — a detailed look at the technology tree and the many setbacks of humanity before it becomes a Cis-Lunar civilization in 2100, an off-Earth civilization by 2200, and then an interstellar civilization in 2300. A Traveller-like or Cepheus Engine-like civilization would be set between 2500 and 3000 AD.
