If Project Gotham Racing and Mario Kart had a baby, you'd get Blur.
Bizarre Creations is a developer of many talents, responsible for a wide-variety of games all in different genres. While they have done quite a bit, they seem to have stuck with the racing genre longer than any other, mostly through their Project Gotham Racing Series. Now that they have been freed from further development of those titles since acquisition by Activision Blizzard, they have had the opportunity to create something in that vein, but fresh and new at the same time. Blur is the result of those efforts, and it is something that will undoubtedly be compelling for fans of arcade-style racing games.
