I've finally got my hands on Wii and I'm playing through Metroid. Sadly, I'm not taking too well to the Wiimote for aiming. I'm a bit too jittery.

So I was wondering if it's possible to play Metroid Prime 3 with the GameCube controller on the Wii?

I don't think so, but isn't it possible to turn down the sensitivity (either on the Wii menu or in MP3)? This may help

yeah, the wii controls totally make this game. try and turn down the sensitivity.

You can also turn off "lock-on free aiming" to go back to MP1 & MP2 lock on target shooting.
