Your people have spent generations underground. They’ve missed the caress of sun on skin, the squelch of soil between toes, the tickle of flies on noses. They emerge, full of wonder, and with absolutely no idea how to grow anything except potatoes.
Rebuild civilization by building huts, harvesting… potatoes and expanding your reborn society to other continents and eventually other planets. Manage resources, discover ancient tech and create a planetary network of colonies to thrive in your solar system.
But the universe is not safe. Ancient, ancestral guardians demand attention and challenge your cities. The planets you inhabit are scarred by the disasters that drove your forebears underground, and those catastrophes will punish poorly managed worlds.
