Pictures shows a reason why 3rd party "core" Wii games don't sell...

I do agree to certain extent, in shops like GAME or HMV shelves are filled with crap games on the Wii, they tend to make deal like 2 for 1 on shovelware, also bundle Wii's with games like guinnes world record and carnival games. Retailers are simply forcing that crap upon customers.
