This game is underappreciated, not that it's an awesome game or anything...
It was great when I first played it, before I had a taste of Need for Speed, or Tony Hawk. And if you're a fan of the TV show, then you're likely to like it enough to pick it up every now and then.
It's definitely not a great game, but the graphics were mediocre for its time, and the sounds always made me laugh.
It wasn't easy, but it wasn't hard, so it was just right. And the various missions you go on are fun and enjoyable.
And it's very enjoyable to free-run every level and try to find all the secret areas, I spent countless hours doing just this back when I used to play it!
Anyway, all in all, a good little game, and if you happen to notice it in a bargain bin or something, get it. It'll give you a few hours of fun even with Burnout Paradise to compete with. :)
