However, friends told me prefer the Kinect, but I will not buy an XBOX now
It was launched when there were few compatible games, Sony now count 80 which is more than respectable.
Even if it brings is more based games (like the wiimote) accessory was adored by my children and is offered at a very attractive price. For once found accessories at a good price / quality ratio is reported.
By cons, when I compare the cost of one pack and separate accessories: Camera Playstation Eye (Playstation Move Compatible) and motion-sensing controller Playstation Move, I do not understand the pricing policy because the cost of the package is the same so that one would hope a small discount.
