I've been playing this. Very fun. Still getting used to the controls, and having issues building speed at times, but I'm doing alright. I don't like that the 'pros' (I've only heard of four or five of them) get blatantly unrealistic levels of speed and air, and that they have suspiciously high scores in competitions. Taking quite a bit of effort to win competitions, especially since I'm still not quite sure what I'm doing at times, and my first 1up match (John Cardiel, I believe) was bullshit. Nonetheless, I am enjoying myself.
Also, thanks to GTA, I instinctively try to pull out a grenade launcher every time I'm hit by a car.
