A name that quite literally means "world on the rim", Rimworld is a colony building / survival game where you are given a bunch of little goobers and have to survive on the planet until you either get sick of it and leave or get sick and die (or get shot and die, or eaten and die, stabbed and die, crushed and die...). So far? I'm enjoying it, even with the base game on its own. Sadly, without the Biotech DLC you cannot get any kids at all so no fatherhood/motherhood for you.
