Regarding Wii FPS controls and CoD3...
It controls well, I admit, but the mouse and nostromo n52 still reign supreme. It's just not as accurate and there are issues with the sensor bar (adjusting your hands, for instance, causes issues on screen). It really offers little benefit.
For precision, as I said, nothing touches a mouse. When I need pinpoint accuracy, the mouse is where it's at. I've also become fond of cinematic, single player FPS titles and I believe the analog stick solution is my favorite. While not quite as accurate (though still plenty so), the movement one receives from analog viewpoint movement is incredibly smooth. I'd imagine most folks couldn't care less, but for me, smooth panning allows a game to just FEEL so good at times. The Wii-mote offers neither the accuracy of a mouse (for games that demand it) nor the smooth rotation of an analog stick. It's right smack in the middle and that's not enough to make up for the shortcomings of the Wii itself.
Really, that doesn't mean it isn't a fun control method. No, I actually wouldn't mind playing more games like that...but CoD3 made me realize just how important visuals (and other associated aspects) are. The game just looks awful for an FPS. I couldn't get into it as a result. I know CoD3, as a game, isn't exactly AAA, but the game bored me to tears and I couldn't stomach more than 30 minutes. Picking up what feels like a 4 year old game isn't going to fly no matter what control scheme I'm using. If I had wanted something unique, I could have grabbed any number of crazy PC accessories and had fun there.
The Wii isn't powerful enough to deliver what I want out of a modern FPS. A new control scheme isn't going to cut it once you've become used to it. The more powerful platforms bring with them impressive visuals, but it goes beyond that and leads into AI, interactions, level sizes, and immersion. The Wii-mote doesn't offer enough to counter what the Wii is lacking. This is exactly what I had expected.
It does give me hope for Metroid Prime 3, however. I'm sure that particular game will look great and now I'm positive that the controls won't become an issue.
