I don’t entirely understand the question. Do I have to carry the food on my back the whole week, or do I just have to carry it to the fully functioning kitchen, and then stash it in the fridge/cabinets? If the latter, is this the same thing as weekly grocery shopping?
I’m not sure I’d call Rimworld “small”, though I guess it is a relatively indie studio. It’s a popular game with a lot of content.
For “small” games, I’d recommend also Nova Drift. It’s sort of asteroids + path of exile + a slight roguelite element.
