@people, Kwaad in particular.
true, Wii tennis etc doesn't work the same as a real tennis swing, but that's not the point (If you had to do a real swing each time, why not go play tennis) the point is that doing a real swing registers in a similar way to if you were playing tennis, so if you want you can act like you are really playing it....That is what makes it realistic.
When i occasionally have a go with Wii tennis in my room, sat up on my bed (TV is at the end of the bed) i do tiny little motions and can quite easily make similar shots to when i do the big swings (like volleys and slices), and if my mind could work it out better i could probably keep the remote pointed at the screen and just flick left and right, which would be even less realistic.....the point is doing the realistic moves works, and gets results.
Edit; extending to warioware (though i havent played it) the game where you "lift weights" or the hula hoop game, both can be done without doing the real actions, but the real actions work (and i assume in these cases make it much more of a challenge) so it is realistic motion controls.
an example that doesn't work in terms of realistic motion is SSXBlur, you perform tricks by drawing weird shapes with the remote nunchuck, not even remotely realistic, but there is little way to perform real snowboard tricks (i think the idea is excellent, but two or three of the shapes seem really difficult, one of them i haven't even managed to do outside of the practising bit). The leaning the nunchuck to steer is excellent though.
