Wii newbie question about controllers and gadgets

Wii gadgets and mote are actually kind of simple.
If you wanna play a game with 4 person, let's say Mario Kart you will need at least 4 Wii mote and if some of the gamers want to put the Wii mote in a Wheel then you'll need a Wheel for each gamer who want it.
Some games use to Nunchuck and if you wanna for example play box with 2 person then you will need 2 Wii mote and 2 Nunchuck.
I bought my Wii few days ago and I am SO excited about it, especially since I connected it to the internt today, can play with the whole world, even with you

You don't need the accessories if you don't want them. You just need the actualy controllers for the games. The driving games I would recommend the wheels. It makes it easier to play and those you can get cheap on e-bay. Also for the golf and tennis honestly you don't need the attachments. They really just sell them to make extra money.

If you want four people you'll have to buy at least the controllers and nunchucks if you want to play with the sensor that is wireless. The old controller I believe you plug in and that you don't have the sensor effect. IT's just like the old fashion nintendo.
