The colonists will need to build water extractors, living quarters, mines and farms, so that they can then continue to build and feed themselves once the initial supplies they landed with have run out. They’ll need to build power generators (solar or wind), and storage batteries as a backup, so that once the sun goes down and the wind eases, the base’s critical life support functions can continue to operate. That tiny handful of people are responsible for landing on a desolate hunk of rock, and immediately getting to work building the foundations of a base. You start out with a tiny population of the bravest colonists of all. Related reading: Another city builder with a similar theme on PlayStation 4 is Aven Colony.
