UPDATE: This only affects the camera motion controls when used in first person.
Hate playing with motion controls? Good news, you can completely turn it off in Super Mario Odyssey!
Super Mario Odyssey has a controls menu which lets you adjust the sensitivity and settings of various controls. For instance, you can adjust the sensitivity of controlling the camera, how weak or strong you want your HD Rumble to be, and much more.
Check out a photo of the controls menu below.
