If you have a Eyefinity/Surround video card, this game looks insane running across 3 monitors. http://www.youtube.com/watch?v=Oc4O4QGgIJc&feature=related
I paid $20 and loved every second of it. It's not perfect, but it's a hell of a lot of fun. I would've been happy with it had I paid $60.
The first one is also good, but this one is definitely better. For those who may be wondering, story-wise, you don't really need to play the first one before you play JC2.
Just got it through a free Blockbuster rental and it's almost a spiritual sequel to San Andreas. It takes itself a little more seriously than Saint's Row but gives you all kinds of weapons and vehicles to have fun with. The missions get a little repetitive and the accents are horrifyingly bad but it's still a great game.
