Time was, video games were a bona fide home for the rhythmically challenged. While all the cooler kids were out dancing the night away, there was much solace to be found in a bout of Mario, or a spin on Sonic with a mug of warm milk before bed. Fast forward to the present day, and you're hard pressed to find a game that doesn't want to test your timing in some form or other - from taking on Dance Central on Kinect to the leagues of Tap Tap games on iPhone, if you're out of time, then you're firmly out of tune.
