You of course use it in WII!
only with wiispeak
The USB ports on the back of the Wii are for connecting accessories such as WiiSpeak or a keyboard.
All on line games for Wii that offer voice communication require the official WiiSpeak peripheral, so no. But for black ops (wii) you cant use WiiSpeak you can only use the "head banger head set".
If you see a pic of the wii speak device on the back of the case then you can use it
You can chat with anyone around the world if they have Wii-Speak and Wi-Fi connection ^_^ http://www.nintendo.com/wii/what/accessories/wiispeak/
If they are Wii games and they are playable (don't wast money on things that LOOK like games like those square boxes that says WiiSpeak that is only useable in the Animal Crossing game) then yes.
It depends on who you play with. To play online, you must get someone else's Animal Crossing Friend Code and when they are online, you can go to their town or they come to yours. Communicaions isn't filtered and you don't need the WiiSpeak to be able to communicate.
MICROPHONE you can't get 1 anyway.... ^Au contraire, mister previous answer. You just have to plug your WiiSpeak microphone to one of the USB ports on the back of the Wii, and place it preferably on top of the sensor bar, or on top of the TV if you have the sensor bar on the bottom. It's only used during online communication, so don't try to think that there's any super-special exclusive content that's microphone only. -TB
Games:WiiGamecube (you need GameCube controller for this)Wiiware (through the internet shop channel)VirtualConsole (through the internet shop channel, Classic controller recommendable and needed a lot of times)Accessories:If you buy old wii without Nintendo at the bottom of the remote, buy MotionPlusSome other like Balance Board for Wii Fit, WiiSpeak for some like The Conduit or Animal Crossing, but really, I recommend buying nothing but additional controllers and nunchuks.Probably the best feature but unofficial and which voids the warranty:HOMEBREW (or How to modify a Wii)Features:Can run apps for WiiCan run games on USB HDDCan restore DVD playbacketc.
Well... depending on what your comparing to. Yes, if comparing to PC, PS3, and Xbox360, but for Wii itself, yes I would say. Bump Mapping is more plentiful -Bump mapping= Textures on objects- then in CODWAW (wii), and Specular map (Shineyness of objects) is upgraded, so scopes and RD sights and the Holographic sight (M4A1 Grenadier) all have reflections. Also, the grass is more... alive... then it was in CODWaW, There are also water reflections. Dynamic Lighting (Shoot gun and light appears around on objects) is also more increased. But again, If your looking for a good Graphics game, Go get a PC/PS3/XBOX360! But if you want good gameplay, stick with the Wii... Lacks WiiSpeak though!
A Wii channel is like an Application on a phone or a Program on a computer. Each Wii channel does a different thing and they are each downloaded from the Wii Shop Channel that comes in the Wii. You must connect to the Internet before you can download any new Channels, but most of them are free of charge. The channels that come free of charge on the Wii are: Disk Channel (Plays a Wii or Gamecube game disk), Mii Channel (Allows you to create your own Wii virtual avatar and tons of other avatars called Miis.), Wii Shop Channel (Download Virtual Console games, WiiWare, use secret channel codes and download free channels[requires internet connection]), Wii Forecast channel (Get the free forecast for your area anytime![requires internet connection]) and the Wii News Channel (Read the latest news on your Wii [requires internet connection]). There are more channels to discover from the Wii Shop Channel via the Internet, but some of the Channels (such as the WiiSpeak channel) require you to buy the software and then enter a unique code to receive a channel that comes free with the software. Hope this helps!
