No, you do not. However there are some things that you can do with the nunchuck that you can't with the regular wii remote.
Wii consoles generally come with the basic controls that you need for one person to play many of their games. This includes the console box, one remote controller and a nunchuk. If you want to play with more than one person you will need to buy at least one more remote controller and nunchuk. In addition you may need to buy additional components for other games.
