The Sims 3 on 3DS is a greatly watered down experience, but contains the core elements of the Sims franchise. You’ll start by creating a character (and can use the console’s cameras to create a not-really version of yourself), and buying him or her a house to live in.
Then it’s time to live. You’ll need to work to earn money, shop to buy furniture and food, and build relationships with other Sims because being a recluse isn’t healthy. StreetPass is ultilised in a neat fashion — allowing the Sims of people you walk pass to pop up in your game, but unfortunately the variety of people types is a bit limited, and it’s a bit weird to see twins with very different names pop by to say hi.
