These are some things you can do if you have Wi-Fi. In Wii, (Mario Kart) you can race people you have never met, or in DS (I dunno, pokemon, maybe) you can trade, battle all around the world. Or if your friend is on te other side of the world, then just email her and when you both are online then you will be able to play with her! Meet new friends!!
