Welcome to the world of business where of course a company is "greedy." Just as you work for profit at your job so does Nintendo and everyone who works there. I completely understand humanity: we all want stuff (which includes food) and need a means to buy it all. Besides, the companies who produce games for Sony and Microsoft are far greedier than Nintendo who just recently started doing paid dlc.

On topic at least the payment is only for the Wii U extra features and not for just playing the games we already bought on the Wii. I don't see myself going for them, but it seems like a neat idea.
