The power-up races are modeled on Mario Kart in every way, are much more rapid and lead to the same tantrums when they will once again bombarded from all sides simultaneously. The AI is well done, is aggressive enough to matter, in my opinion, play strong enough and cheating not noticeably especially.
In single player mode, the game falls on the other hand slightly, the career is a disjointed series of races without any story. The checkpoint races are frustrating only Demolierungsrennen great fun.
Overall Blur is an extremely fun game when you catch up with friends in split-screen will measure (on a large screen TV); alone it's still a solid arcade racing game for in between, if you can do without a real career mode.
