It definitely helps, but only if you're interested in the game. Granted with respect to children and the audience their trying to appeal to this game fits the bill. I don't know I would say it is competitive with the Wii though, if I were a casual gamer I would still go with the Wii.
Also I'm pretty sure that Kinect games will retail for $49.99 not $59.99, but that doesn't really matter.
