First off, I'd like to say that I'm a motion gaming addict. Microsoft offers this package, which is their best package to date. If you plan on just buying this package, and a couple other Microsoft games, I'd say go for it. Gunstringer, in my opinion, shows off what the Kinect can do, as well as Fruit Ninja Kinect. Most people who have played Kinect Adventures get bored after a week, although when I first played it, it was fascinating.
In Gunstringer, you raise your left arm out and navigate your character. Your right arm is your trigger arm, and when you roll over characters, you raise your arm to shoot. It's a lot of fun, as I have to say that it's a good choice for this package, although there is an adult theme that one must be aware of. Fruit Ninja Kinect is a downloadable title, and has high replayability value. It's lots of fun to swipe your arm across the picture to chop fruits in half.
Now, for my gripes. I've always thought that boxing and tennis would be the hottest selling games, and games that wouldn't require much space. Exercise games are awesome also, but until the Kinect can allow you to play in a smaller space, there is a problem a lot of people will have. Many users claim you only need 6 feet, but I find this untrue. 6 feet only will work with a lot of games(the games in this package work great with only 6 feet), but I've found that when other developers games all of a sudden require me to step back, the whole formula doesn't work.
Most of the other developers games are by Ubisoft and THQ. Ubisoft is better of the two, but in my opinion, neither can compete with a game developed by Microsoft, which really takes limited space into account.
Kinect is still based off of hope for the future:
A year ago, many high reviews based this off of HOPE. A year later, and I'd say there are only a handful Microsoft exclusives, and a lot is still based off of hope. I'd say the best of the bunch are the Kinect Sports 1 and 2, but I'd prefer to see each sport focused on more, in a stand alone title like a Grand Slam Tennis, for instance. Star Wars Kinect seems to be promising, but as of today the release date is December 31. 2012.
In conclusion, I feel this is a generous deal by Microsoft for the 2011 holiday season, and is a bargain with the included games worth fifty dollars. Who knows? In a few months, you may end up like me, always checking to see if there are any new releases for the Kinect. Have a good one. Peace out!
