Well i dont intend at all to sell my Wii btw lolx.
And Wii = Moving around to play a game = Yup it is Famous for that but after being a Wii owner for some time , games im playing usually makes me Sit down and dont move an inch to it or as describe lying down on the bed to play.
Thats wad i often do UNLESS is RB ( involves guitar and drums , still im sitting down and pressing buttons lolx , as for drums still sitting down and hit the drum pads) Or maybe im a lazy player but i dont see why it has to move around or maybe some ppl out there only buys wii for WII SPORTS ?

Again as for my survey or experienced

Cos i have teman my friends to COD second hand wii few times.
And those sellers end up selling , i Totally understands y ( probably )
Seeing the games that own from the seller , u know y they are selling the Wii lolx... ( i.e Games ive seldom or never heard of )

So ask the seller again , y selling ar?
Answer - nothing to play
Answer - Finish Wii Sporting
Answer - Bought Another Console

But actually seriously when u see their selection of games they owned
You know Y they are selling.

If i ever buy another gaming console
Wii will still be next to me , Will probably only sell it cos a NEW HD WII comes into the market.

Yahlor , u scratch ur head when u see the sellers games.
A few times adi i teman different friends COD their Wii as Buyers
