This would essentially be a normal planet with no plotting allowed. A place to explore (that doesn’t go poof a couple weeks later). A place to harvest beans without gleaming towns crushing nature underfoot. A planet with beautiful colors not found in the regular universe. An exo that doesn’t cost a fortune to warp to, but as a catch it also doesn’t spawn exo drops.
Maybe there’s something else special about these worlds… maybe you can breathe underwater? Or jump 2x higher? Who knows.
