I've played several competitive FPS's on my 360 and me and most of my friends agree that wii-remote controls for FPS's make the game way less skilled and much slower than usual, playing Call of Duty 3 on the Wii was like playing Halo 3 with 10 sensitivity, it's also quicker to react with a button press than swinging your remote in several different directions, my last point is that there isn't enough buttons on the Wii-remote and Nunchuck within close proximity of each other to perform all the desired actions, with reload, jump, melee, switch weapons, switch grenades, pick up weapon, use equipment, and throw grenades, it becomes almost impossible to move, jump, and throw a grenade at the same time or it might force you to let go of the jump button to perform various actions, etc.
