You should keep your living room clean anyway.
If you're the kind of person who does a lot of gaming, odds are good that you aren't the kind of person who keeps a spotless house. That's a bit of a generalization, but most gamers are young people, and playing video games is way more fun than organizing your living room. Kinect may end up having a positive effect on the millions of dirty bachelors and bachelorettes nationwide.
TechRadar reports that a developer diary has revealed that the Kinect needs an orderly room to work properly. If piles of clothing and boxes and other detritus fill the gaming area, it will have difficulty detecting where you are in relation to your environment.
This sounds kind of annoying to deal with, but it isn't like tidier nerds could possibly be a bad thing, right?
