I just completed it i had for a billion years but never played it until last week. Although i thought the racing aspect of the game was quite nice maybe a bit 1 dimensional, could have been more variating tracks but nevertheless quite fun.
However the storyline was weak! I mean there were like only 5 cutscenes and nothing happened with the girl (mellisa) it was just race race and race. But I have the feeling that the devs had planned a deeper plot but just abondened it. Very Disapointed with the underground mode.
