Although the core concept of the game—race jet-powered bikes on gravity-defying tracks while dueling with other racers—remains unchanged, some remarkably subtle changes (not to mention some not-so-subtle ones) have transformed Extreme G from a mediocre trend-follower to a well executed, exhilarating racer.
When the novelty of the new features wear off, Extreme G III shows the chinks in its armor. Although vast, the environments in the game are rather plain and in many areas, they are downright barren. Admittedly this probably responsible for the silky smooth framerates we praised it for, but more variety in the surroundings would have gone a long way toward giving this game some personality.
