A great sequel that builds a lot on the bones of the first game while staying true to the fast paced racing that made the first one solid. Most dramatically, tracks now have changes in elevation which adds a little visual variety as you tear around the tracks. It doesn't effect gameplay much, but careening over the tops of hills looks very cool. The upgrade system is also more elaborate since you now buy upgrades in a shop between races. The game still feels really good and goes nice and fast.
