The selection of Xbox Live racers on Windows Phone varies widely in quality. Hydro Thunder GO and Need for Speed Undercover occupy the top end of the quality spectrum, while Cro-Mag Rally sits in a pool of ick at the bottom. Sadly, Cro-Mag Rally was also the only mobile Live kart racer for almost a year. Fast-forward to May 2012 and Namco Bandai surprised us all with Pac-Man Kart Rally. While it never matches the lofty quality bar set by the Mario Kart series, Namco’s racer still manages to be pretty fun, easily surpassing its only other Windows Phone competitor.
