Isn't this
good though? If the problem is the 'deluge of shovel-ware' then having all of these third parties
not being unable to turn a respectable profit with them is good news. It's capitalism at work, right? You make no money on crappy games so you stop making crappy games.
Though, I suspect they do actually make money on the Wii. The sheer number of crappy games coming out for the Wii would indicate that the 'market' believes these crappy games will sell enough to get a decent ROI.
This leaves one of two possibilities:
A) You made up your previous fact.
B) These third parties are all to dumb to realize that making these games isn't making them any money.
I'm betting on A.
