How would your sim live, like what would you put in the house and help fill their needs? Example; Cooking Lights Entertainment Etc... I know the waterfall and swimming in the beach fills hyg...
It depends on where you live I guess; but where I live it means not depending on communities and services which often includes plumbing, etc...it isn't impossible to use generators; but usually it is hospitals and stores that have them then most households and not sure if Sims 4 will bring that option into the game as I think they are going more for a challenge to see how creative simmers can be when surviving and generators would kind of take away from that.
