Metroid: Other M is strictly a Wiimote controlled game. The buttons just don't seem plentiful enough to control Samus in 2D or 3D space. It's hard to think how you use rockets and other equipment using the Wiimote held sideways. On top of that, you can also switch to First Person mode on the fly, but that is also limited to the Wiimote. When you enter First Person mode, you have to turn your Wiimote vertically so you can point and shoot.
