Some games come with the Wii Accessories, the game needs, such as Guitar Hero or Dance Dance Revolution, but some games you download will require the Classic Controller or the Gamecube Controller, both of which are sold separately (in the case of the Gamecube, not at all).
There’s also a Wii Speak accessory, but if you don’t have any friends with that, then it’s useless to you, because you need friend codes to use this, most of the time. The only games compatible with this are one game I can’t remember the name of, and Animal Crossing City Folk, both of which need friend codes for any multiplayer, I believe.
