Dave Mirra 2 is much like its predecessor in that you take 14 pro BMX riders through the game's 10 different levels. Along the way, you are required to complete a variety of challenges, from high scores to long grinds. Other pro riders populate each level, and they give you the more difficult challenges, mostly just higher scores to achieve.
Your motivation for all of this is to unlock not only tougher levels, but better bikes for your favorite pro rider. Just like in SSX, as you move through the game, you progressively get better gear. But the bikes in Dave Mirra 2 excel in different areas, giving you a wide selection to choose from, instead of just being forced to use the best one around.
The levels themselves are huge, with plenty of things to utilize for your riding pleasure, and each setting is so varied from the next that you'll really appreciate completing the challenges. Each level usually has some type of moving objects in it, from go-carts to freight trains, which you can grind on for mass points. A lot of them are used in the more complex of challenges, like jumping through an open container on the train.
The thing that will have you coming back for more, though, is the level editor. Here, you pick the theme of the level, and then you can fill it to the brim with a most excellent assortment of objects. Making the park of your dreams is at your fingertips here, and only a few (ok, a whole lot) of clicks away.
