its very simple in a way.. you need health ,energy and to be rested before adventuring.. so you can find or build a rough hut or make it more elaborate.. it will give you a rested bonus and a place to sleep.while you seek out different resources which could make weapons tools food thereby increasing your health and stamina.. but like real life you need to keep eating somewhat regularly or u wont have enuf health to survive a hit or stamina to wield a weapon.. so building a bsae could be part of your plan or you could settle on more humble housing and improve it a little..
