Well Santa first things first.
1.HP Compac Laptop Thats all Im saying on that matter.(my xmas list).
The Wii plays Wii games of course there are hundreds from Aliens to Balloon popping.
It also plays the Gamecube games. The Wii Shop channels sells games you can download although personally I think they stink except for Tetris.
You can get tons of different games.
Personally I have never played videos. I am an adult yes... I bought a wii and Super Smash Brothers Brawl and was hooked. So try renting games first at 50.00 a game to buy if you hate it well..
The Wii Mot is needed to start all games and to go through the menu.
You can choose to use a gamecube controller to play or with an adapter Playstation controller and soon X-box. Theres even an adapter to use the old SNES ones.
You will find many others: guns for shooting, golf club for golf games, bats for baseball games etc.
Edit: Go to the Nintendo Channel on the Wii. Watch the videos of the games Wii offers. That helps to see if you may be interested.
Playing online is fun. Each game is different unfortunately Wii games online are limited.
Mario Kart is a good one. Again the bad part is 4 people cant play online on the same Wii.
You dont need to with 4 people though. In brawl 3 people can play on the same wii but there must be a 4th person on a different Wii at same time (with friends). If you shop at Walmart look at their Wii games section to see whats available.
To play online you need high speed dsl/cable internet and a wireless router. The Wii has a built in Wifi adapter. Or you can hard wire it via ethernet cord and a lan adapter. Your Wii manual is very easy to understand and has easy and clear instructions.
Theres also a new Poker game out. Like music? Check out the Rock Band stuff. You can play guitar or drums along with it or god forbid SING lol.
Working on a list for Santa
