My heading may be a little harsh, not sure if Nintendo is attacking or just trying to curve the sales of used games. No matter the reason, when you purchase Animal crossing with Wii Speak. You will receive a code that is to be used to download the Wii Speak channel. Once used this code can not be used again, which may cause a problem if you buy it used. There is not word yet if you can buy another code or not, but it looks like you may be out of luck.
