Colony simulators can be overwhelming. Games like Dwarf Fortress and RimWorld use migration as both a fuel and a pressure valve, delivering caravan after caravan of fresh colonists at regular intervals to ensure the centre of balance of your community is always tipping forwards. Space Haven, which is set not on the filthy ground but in that big empty boob we call space>, flip-turns the usual template upside down. You command a ship that quite literally is always moving forwards, resources are scavenged from passing derelict hulls, and fresh crew pilfered from other ships.
