Factorio is almost exclusively about factory building and automation. Rimworld is much more of a social/survival game, with hunting, gathering, cooking, diseases, invaders, exploration, character emotions, etc. Factorio has basically none of that; it's much more about plumbing together inputs and outputs into increasingly complex and useful items. The survival aspect of Factorio is just that you are surrounded by bugs that will attack you if you pollute too much or antagonize them.
