This game is quite simply, the hot shit.
It seems like they took all the best parts of all the past mario karts and put it into a blender and out came this wonderful game. The hop of old skool is back, but with the power slide of DD put there as well. It is also easier to bump the other cars around now, so all that Burnout time making me aggressive is paying off here.
I only played for about an hour last night, getting ready for a marathon tonight of the game. Now all I need is a wireless router and I will be in heaven.
But seriously, any doubts you have about this game, put them to rest. This is one of those games that the moment you start playing, you are filled with that sense of glee that only the great games can give you.
