Unpacking the boxes…
One person, a small flat, and everything after: friends, a partner, a family, a house of your own.
Everything starts with one person. Edit them to choose a name, look, age, height, traits, aspiration and career.
One person, a first flat and a first job. Keep them fed, rested and happy, grow their skills, finish quests to make room for a housemate, a partner and children, and save up for a bigger flat and then a house.
