I have only recently got this game, and the Kinect. I haven't been on it much so far, but the game does have a lot of good content and mini games that you would do in athletics stadium. Although this is good it's a difficult game to play in a multi player game, as you need a lot of room and space to get the movements right, you have to move a lot of space to do this. If you have enough space this game will be a great buy as it has a lot of variety within it.
Easy to pick up the skills to start playing as the controls are so intuitive, but opponents/challenges naturally become tougher as you progress thereby ensuring that you keep coming back for more. The level-up scheme also provides avatar awards and the like.
Great to play alone or with a friend, and the video replays of your often strenuous efforts are good fun to watch. You don't need to be fit to play the game but some of the challenges will leave you gasping for breath as you strive to beat a friend on the track.
Connect to X-Box Live and download some free mini-games as an add-on, which makes the purchase even better value.
Has a fab soundtrack too, you'll recognise loads of songs and be singing along during the loading sections.
My least favourite aspect is the ten-pin bowling game - but that's still miles better than the WiiSports version and there's so much else to do, Kinect: Sports still feels like a complete game without it.
