This is a faulty argument from the get go. Retailers keep reordering Carnival Games because it keeps selling. A nice steady dependable amount month in, month out. Metroid Prime no longer sells so they don't bother to reorder it when it sells out - why would they?
'Core' type games tend to only sell for the first two months and then are effectively dead. 'Casual' games tend to sell consistantly for months and months.
The exception here is shovelware. Shovelware doesn't sell at all. So it sits and sits on shelves until ultimately it gets put in the bargain bin and continually discounted until someone finally takes it off the stores hands. This DOES suck up shelf space that could better goto House of the Dead or Hanna Montana. So stores don't like it either.
