Kotaku.com editor states, "I like driving games. Love 'em! Can't get enough of them. But as I've played more and more over the years, I've grown to develop a keen sense of what it is, exactly, I like about them. I like fun. I dig the sensation that I'm driving really really fast in a really really expensive car, and having to drive like a maniac to beat a bunch of other maniacs driving fast, expensive cars.
Lucky for me, you, Bizarre and Microsoft, then, that's exactly what PGR4 delivers. It's fun. Buckets full of bucketloads of fun. The core driving mechanics seem to be the same as PGR3, but just about everything else has been tweaked, improved or added to improve on the predecessor. Tracks are better, opponents more interesting, progression has been overhauled, the graphics are slicker, bikes add a whole new dimension to the game...see? Everything's been changed, and it's been changed for the better."
