Retrotechnological movement developed during the Expansion Era, sometimes seen as a counter-reaction to Keterism and other ultra-high tech lifestyle choices. The retro-lifestyle is often seen as a less demanding, lower-stress, more natural option, although many retroist societies do include certain hi-tech amenities such as backup tech and Known Net access.
A number of planets and habitats in the Middle Regions follow retrotechnological policies; the chosen level of technology may be middletech, low-tech or even primtech. Most independent retroist worlds have since then been absorbed by the various empires, especially the Terran Federation.
