Tony Hawk does it again.
The controls are great. It actully incorporates the touch screen in a way that adds to the game. The player uses the touch screen to activate certain special tricks, called "touch specials". There is also an matix-esqe focus button (it slows down the game allowing you to pull off tricks easier) on the touch screen. The button controls use every main button on the ds. They are pretty easy to use.
The graphics are cel-shaded and are some of the best cel-shaded art I have seen in a game. Everything moves smoothly on the screen. You only get loading times when you move from one level to another, and they are fast.
The art in the cut scenes is pretty much comic book stlye.
The gameplay is the best part. The player can pull off tricks very easily. The focus ability does help you pull off tricks, but it is frustrating when it stops in the middle of a combo and the player can end up wiping out because they weren't ready for it. Other then that, the game play is great.
This one of the best Tony Hawk games ever.
