''There's not a whole lot in the single-player campaign to get excited about, other than to sacrifice a few hours to unlock all the hidden characters like Toadette, the toddler versions of Mario, Luigi and Peach, Baby Koopa, and several others. Upon meeting certain conditions in the Grand Prix and Time Trials will also gradually reveal new racing circuits and different vehicles (now featuring 20% more variety thanks to the debut of bikes, yay!). The weight class system is still in full effect here, allowing players to carefully plot their strategies before hitting the track, rather than creating a handicap against inferior competition. Personally, I always opt for a medium-weight class bike that has a balanced amount of speed and acceleration, as it allows me to easily elude the heavier class vehicles and maneuver in tight corners. Any diehard fan can tell you that there's no specific vehicle that will guarantee victory. Much of your success comes down to racing skill (and the sporadic randomness and luck that ensues) in each match. That being said, in the right hands, even those who opt for the heavier vehicles can score the occasional victory.''
