Disgrunt: Most reviews state that the waggle just sucks for most of the basic manuevers. It works "ok" for the paintbrush parts, but all the rest of the game it doesn't.
Personally, going by my experience with the Wii, I can't imagine the cursor moving fast enough for me in combat. Its always kind of sluggish moving around, and in the heat of battle I know I can't count on MY ability to coach it into a proper shape. Analog just made quick paintbrush movements really easy.
