Joking aside. I found that I could do passably well on low fortitude (1 or 2 in living off the land, if memory serves), but with a huge farm. I think I had upwards of 20 corn growing and at least ten of every other 'most needed crop'. Then supplement meat by ranging far and wide long into the night (while also keeping a keen eye out for any Bob's Boars). But that would not hold true in A18 with the increase demands on farming. With three ppl, we're not painfully struggling, but I always have an eye on our food stores. If spoilage were A THING, we... well... I'd have to rethink my build MASSIVELY. Much less with 7 ppl.
