answer:When you buy the Wii, it should come with one Wii remote, one nunchuck, one sensor bar, the actual unit, a stand, a power cable, and an a/v cable. Make sure you have all of those. If you want more than one person to play at a time, you’ll have to buy additional nunchucks and remotes. You may want to get some covers for them, I don’t know what they’re called. Anyway, they help pad the remotes for when they get dropped, which is often enough. Some games require the use of a MotionPlus accessory that attaches to the remote and gives better movement tracking. You’ll have to get more than one, if you want all players to be covered. There are other accessories I consider to be optional. There’s a wheel you can use for driving games, sports equipment attachments (tennis, golf, boxing), amongst others. The balance board and Wii Fit are pretty cool and I’m going to get them when I can afford it. I particularly like the yoga. Then, of course, one of the band games.. those are super fun. :)
