Tried the Topspin 4 demo with Move. Again it’s just swinging, and not about position. You move with the nav controller in your left hand and swing with the Move controller in your right. It didn’t adjust for body position, but that’s just the game. It’s not like say table tennis in Sports Champion.
At the end moving your character with an analog stick while feverishly swinging your Move controller, it didn’t work smooth. I’m slowly pushing my analog stick to move my character around, meanwhile swinging my arm around. I don’t think it even differentiated properly enough between a back and front swing. Very tacked on, could’ve been fun, was not.
