I liked this review a lot. I must admit that my impression of the game was mainly "an offbeat-looking GTA clone", but from the sound of the review there's more variety in the game that I was expecting.
And the game is indeed pretty much dirt cheap by now. Saw it for $15 CAD (so it should be $10 USD) at EB recently, and even a couple of months before, it wasn't much higher. I haven't seen any sales figures, but I figure this one wasn't so popular.
