Generally, The Sims 3 game will be similar to others in the series. Before commencing play, you will first create a virtual family which will then be moved into a neighborhood. Your family can be of any race or creed or body style. Once in the neighborhood, you'll be prompted to buy a house. You'll begin the game with a set amount of currency, called simoleans.
