I don't like the idea of buying a games console for the purpose of playing one or two games on it. Sure, buying more games equals more money, but video gaming in general is just a pricy hobby. It's your own choice, but personally, I hate seeing something left to collect dust when it can be put away, sold or put to use other use. (Like a foot stool.)
Wii U WAS pretty dead during its first year. Hell, I played more Wii games at the time than Wii U. But when Pikmin 3 came around, more and more Wii U games were launched and now I'm at the point of choosing which games I wanna buy.
Pikmin 3, Wind Waker, Sonic Racing Transformed, Rayman Legends, Wondeful 101 and Sonic Lost World are what I've played and enjoyed so far, with more games coming in future I can't wait to play. (NSMBU was just disappointing.)
