Super Mario Galaxy - A note on controls in the NVIDIA Shield port

As you might remember, Super Mario Galaxy utilized motion controls to make Mario spin. It was a pretty big part of the game. The NVIDIA Shield doesn't have any motion sensing tech, so they devs had to use a workaround. Now you can spin by simply pressing the X button. I imagine a few Galaxy players would have much rather played that way to begin with!
