I think the accuracy is determined by how accurately you pull the right joystick back and forward. Power, I found, is best done by a fluid motion of back and up with barely any hesitation in the sitting back position. And with the passing system, you can run just as fast with the options up. There is no X pass option, so that leaves X for turbo for running around in the pocket.
Price tag says $49.99, but my dad got it for $37 right when Circut City opened I'll play it later. I have a party for my work in a lil bit...
