Call of Duty 3
This is my Wii-Mote, this is my gun
The first-person shooter has hardly been the bread and butter of any Nintendo box (blah blah Goldeneye) but when the Wii remote was first unveiled, one of the big questions was how it would fare in a straight-up action game. With Metroid delayed, this port of Call of Duty 3 is our first glimpse of the remote in the FPS wild. It's a pretty impressive beast.
The good news, both for Nintendo and for fans, is that the remote works quite well as a stand-in for the barrel of your gun, with precision shots no problem, even on the move. You might get a little bit tired holding the remote out to aim and shoot for hours on end, even using the smallest possible movements. Want to win a war? Best develop those triceps and biceps.
Unlike your trusty PC mouse pointer, however, forget about customizing controls. Basic response and movement speed are fine, with your character turning faster as you move the pointer towards the edge of the screen. Want to tweak that response? It ain't happening. This is the Army, son. Love it or leave it.
