First, it is Wii not Vii.
All stores in 黃金商場 almost the same. Check price one by one.
日本版's box is in Japanese. 美國版's box is in English also has Wii Sport.
日本版 has one console, one wiimote, and one nunchuk. 美國版 has all above and Wii Sport. New 美國版 also has Wii Jackets (protector for the remote control).
Wii大概幾錢??? Don't know the price now. 美國版 is a bit more expensive than 日本版 though.
仲有,點試機??? Just turn it on and play a short while. Very easy.
