After that's done, I will have a large, poorly educated population with a trait that makes them more likely to freak out during disasters. Right now I'm scrambling to finish a mega dome to just fill with housing to get them all to stop becoming renegades and draining morale, comfort, and sanity. Then, less than one sol later, a ship carrying 100 refugees arrived. 60 people died before I was able to reconnect that dome. Then I got bombarded by hostile forces for supplying the USA with rare metals. Then a second one showed up, ok, things are kinda stressful, but I just finished a new dome at the base of the valley near some good metal/rare metal deposits, so they can work there to grow my industry. They had a lot of flaws and there wasn't really enough housing for them, but I took them in anyway because I could use the workforce to expand my colony. Decisions where to land their first rocket and where to expand require careful planning. Resources feel scarce, as resource depletion and scarcity are constant problems players face. Resources are very different from one another in terms of acquisition, production, and/or purpose. Then a rocket with 50 refugees showed up. Resources are gathered and used in Surviving Mars to develop the tools and structures necessary to survive. As soon as those were finished, my manpower shortage disappeared. The second was a breakthrough that let seniors work. The first was a regular tech that pushed back retirement and death ages, keeping people in the workforce longer. My expansion was crippled from lack of people, until I got two techs.
So, last war USA run, I got cut off from resupply and new colonists mid game, just after putting down a third medium dome.
