Kinect sports expands on the amount of sports and functionality by allowing players to use their legs instead of just swinging their arms wildly. Anyone that has played the Wii sports games knows that the motion detector can sometimes be finicky, and others downright frustrating. The Kinect does a wonderful job of tracking and integrates a player's movements for most of the sports and games that are included.
The graphics are understated, and very easy on the eyes the interface is very simple to use and understand. The game is very clearly geared toward family fun, or for groups of friends to pick up and play. Customization is nothing ground breaking, though you can build up your avatars statistics and acquire awards and trophies.
Kinect sports includes: Boxing, track, volleyball, soccer, bowling and ping pong (referred to as table tennis by the overtly rabid fans of the "sport").
Boxing is great fun, and was probably the most seamless transition from real life to digital. My abs and neck have never hurt so badly from playing video games. There were a few tracking hiccups while trying to stay within the virtual area, but most of the problems were with me banging my shin on my coffee table.
Volleyball was the second best portion of the game. Though your player is automatically moved around the sand for you, you still have a good amount of control. Spiking and scoring is very satisfying.
Table tennis was exciting and was even more punishing on my sore abs. The animations are really fun to watch in this game. Be wary of multiplayer, having multiple arms flailing can be quite dangerous.
Bowling, I have to say, was a pretty big disappointment. The mode doesn't seem very deep. It makes sense that you don't need to run towards the television, but something just felt a little dry about it. I'm not sure how the Kinect tracks your English and draw etc. and it seems like it wasn't very well thought out. I do like how you can just pick your ball, place your feet, and throw the ball however.
Track and field took me back to the days of the old Nintendo game version. This game really gets the blood flowing while it has you run in place and jump over hurdles etc. I wasn't expecting a great deal of fun out of this, but once my body gets accustomed to moving so much, I can really see using this game a lot.
Soccer is the clear loser of the modes. You are mostly stationary while most of the work is done. Standing in place and kicking and passing are not most people's idea of fun.
I wasn't expecting much outside of a few minutes of fun with Kinect sports, but really came away impressed. After so many motion debacles, and the corny marketing of the Kinect, (I think this was the common consensus among most gamers) I can be forgiven for not having high expectations.
