I haven't done a careful look at Rimworld, but the impression I got with what I have seen is there's more combat/conflict than I care for. I like building games to be centered on building. When I played my many hundreds of hours of SimCity 2000, I played with the disasters turned off. Are there options in Rimworld to reduce the amount of combat you have?
