Why do people claimed only Nintendo games sell on Nintendo platforms as if a bad thing?

With every generation I buy less 3rd party games on Nintendo system. My Wii is basically a Nintendo 1st party machine. I didn't want motion controls but I had to accept them to play Zelda, Mario, Metroid, etc. I had no reason to buy any 3rd party games when I could buy all the best 3rd party games on other platforms.

It's not that 3rd parties can't compete with Nintendo's 1st party games. It's that people don't buy Wii's to play gimped MW3.

Right, and if we re all in agreement tht that's the fault of the third parties, then there's no argument.
