Pros: Cheap, fun, challenging
Cons: Can get frustrating

Tony Hawk 4 is the 8th game that I got for my X box since buying it about 20 months ago, pretty decent game especially considering the price (29$ at Walmart). The game get progressively harder as it goes on so if you find the challenges a little easy in the first couple of levels just wait a while, they get pretty hard pretty fast. I am doing alright and so far have a max of about 500,000 points in a 2 minute trial. There are a few of the combo's that I find really hard like in London but the only take time to figure out. Create a character is pretty cool, lots of clothing and you can customize the color, I prefer shirtless with LOTS of tattoos.
To close, good bang for the buck, very competitive in the 2 player mode.
