That's not what I meant though, you obviously wouldn't want to be pointing at the sensor bar the whole time. I meant that you are "pointing" at the sensor, as in the sensor picks up your motion but you can't point on your TV and try to hit what you're pointing at. So basically you're not pointing at the sensor bar literally but that's what's picking up your movements in a game where they use the wii-mote as a pointer, like in FPS games, not the TV itself. Let me try and explain...
You are on your couch playing Red Steel and you aim at point A on your television, you shoot, chances are you're not going to hit that point. You have to aim with the wii-mote so your reticule on-screen will be on point A and then you shoot. In a light gun game all you do is point and shoot, with the Wii you have to aim with the wii-mote and then you shoot but you won't necessarily be aiming at what you're shooting on the TV. It's similar, yes, but it's not the same as a light gun point and shoot interface. Here is another example: let's say you set up your Wii in an empty and spacious room, the TV you are using is in the middle. Now, let's say you place your sensor bar about ten feet behind your TV, you go sit down behind your TV and start playing Red Steel, you're movements will still be picked up by the sensor and you would still be able to play Red Steel without actually pointing at your screen. Now try and do this with a light gun game and...it won't work.
The sensor bar doesn't send out an IR field, it only uses IR LEDs which are the sensors on each end of the sensor bar and even though you don't have to point precisely at the sensor bar you still have to point in it's direction or it won't work right. If you have the sensor bar to your right side and you are holding the wii-mote like you do in Red Steel or TP the sensor bar is going to think you are holding the wii-mote like you would in Excite Truck since it senses it's position and movements. Did that make sense?
Trust me on this one, I have researched and studied all of the abilities of the wii-mote and I know what it's capable of as well as what it's not cabable of. Actually it is capable of light gun accuracy but it's hard work to implement it and Nintendo, as well as other developers, aren't working on that. Right now the FPS games that are on the Wii: MP3, Red Steel, CoD 3, and Far Cry are all using controls like a typical FPS game, with added motion controls of course, and not like light gun games. You can try this yourself when you guys get the Wii and a FPS game.
Trust me, I know what I'm talking about.
