Man, if it's anything like the Gamepad with even more comfortable design than I am game. Super Mario Maker wouldn't have been all that viable without it (in my opinion... I know some people build without it.... SOMEHOW) and I was insanely surprised when i got the Wii U home on day one and pulled out this HUGE controller which surprisingly doesn't get all that tiring from using for even a few hours at a time. Although I might have larger and stronger hands than the average person since I work at a factory six days a week.... But I definitely enjoy it. However I was also one of the odd-folks who loved the original Xbox controller too. The one prior to the S edition that is now the standard for Microsoft consoles.
I use that big bulky bitch of a controller every time I play a game on my Xbox. Although the only games I really play on there anymore are Silent Hill 2 and 4... I like changing up the consoles every once in awhile for those games lol
