Before going any further, I tested the game under every circumstance I could. I re-calibrated the Kinect, even using the face card; brought in a pair of lights from work; purchased a Kinect mount for the back of my TV; and even tried it at a friend's house. If there's an ideal place to play the game, I couldn't find it, which is a shame because I really wanted to enjoy Wipeout: In the Zone
and thought it would be a "Must Play" when friends came over.
If you own a Kinect, you know there are still issues that need to be worked out with the controller. I've had problems with some games not reading movements, but not as much as Wipeout: In the Zone. I got the best results using over-exaggerated motions, though these weren't the most comfortable actions. I had to practically goose-step to get my Avatar to walk; running was even harder. One obstacle requires walking while balancing, which is really hard when you're forced to use high-knee steps. Even with the big motions, the motions wouldn't always go through.
Some of the problems seem related to the amount of lag between movement and it happening on the screen. I expect some lag between big motions, like jumps or running, but there's a slow pick-up on even small gestures. Holding your hands in front of your body is supposed to hit the brakes, but it doesn't work all the time. The lag gets so bad at times it will read the wrong motion. Sometimes jumps are read as ducks or the hand motion causes you to walk backwards. Unless you manage to find a sweet spot, there's no telling what will happen.
Wipeout: In the Zone is more potential than product. That doesn't mean it is a total wash; you can still have fun with friends if you just want to watch each other stumble through obstacle courses. At the same time, the fun of friendly humiliation is brief. With a few tweaks Wipeout: In the Zone could be great, but until that time you should probably avoid the purchase.
