I used to wonder how certain games could possibly be played with Kinect rather than a controller. But now that I've seen the way several games are played, I can confidently tell you Kinect is going to make games far more popular with females, kids, and even older people, just like the Wii did. There is one reason for this: Simplicity.
Games become so much easier and better to play with Kinect. When you play Forza Motorsport 4 with Kinect, your only responsibility is using your hands as the steering wheel...and that's it. The game does the braking and acceleration for you. This type of simplicity is exactly what females and kids desire, because it brings back an arcade style of fun!
Hardcore gamers will probably want to stick with the complex motions of control pads and force-feedback race wheels. But most people really will love the added simplicity Kinect brings to the table. With Kinect, you won't need to spend hours mastering the complex techniques of every game. In Forza 4, you won't need to learn exact moments when you should brake, accelerate, and when you should start slowing down. Just use your hands to drive in a fun way and you will do just that -- have fun!
The same concept applies to games like Ghost Recon and Gears of War. When using Kinect, you won't be responsible for handling complex responsibilities such as running and dodging. You will control those parts of the game if you choose to use a control pad, but while using Kinect the game will do a lot of that stuff for you. When playing with Kinect, you will just need to do basic things like fire, reload, and switch weapons. This form of simplicity makes complex games fun for inexperienced gamers!
Kinect is currently in the Guinness Book of World Records as the fastest-selling electronic item in history. I have no doubt the success of Kinect will continue in 2011. Kinect turns very deep games such as Forza Motorsport 4 and Ghost Recon into simple games anyone can start having fun with at any time, just like at an arcade.
