Zavvi have seen the future and it involves everyone heavily discounting Fighter Within thanks to the stinky scores it's been racking up. They're selling it for £15 cheaper than the other sites at the moment. Matt's take on the preview build of the Kinect-only fighter was that it was a bit of a laugh in two player, but you it lacks the depth of a regular fighting game. If it's on someone's Xmas list, this is a great price, although it could get cheaper thanks to those review scores.
