"It does take a few moments to get used to Natal. There is a small amount of lag between when you think you're starting to move and when the avatar on the screen actually does move. Swiping at a ball just before it goes by you will just make you look silly. And if you try to stand perfectly still, you'll notice a little bit of a jittery motion on the avatar."
What do you think?
Game issues in need to be polished and/or Natal 30 fps (at maximum) motion tracking is showing some limitatios to fast movements?
