i just picked up the game and its awsome. its a continuation of the last game (Most Wanted) where it picks up right after you excaped. when u pick your first car you choose the direction the game goes for you basically because there are 3 groups in the game. muscel, exotic and tuner so whatever car you choose thats the group you are in or so it seems.
you are back in the town that you were in, in underground 2
