Well, I already have an xbox 360 for myself. This purchase was for my niece, who has gone on forever about getting a kinect for her room. So, I bought her this one and so far, she's loving every minute of it. Kinect Adventures, she says, is fun and a good party game and she loves playing the carnival game. I couldn't get into that one myself but she seems to enjoy it tons.
Also, she's definitely loving all the kinect apps on the marketplace and now she wants dance central 2.
Anyway, this package seems to be a wonderful package for all ages, especially for the kids, and she just can't get enough of it.
