Overall I'm not disappointed, as I've yet to be from any of the Mario Kart series. It delivers the game play fans look for while carefully adding new features to enhance that game play without alienating older fans. My only qualm with this game really is that with so many weapons, many a little more powerful than need be, it takes away from a need for driving skills. A player can take every turn flawlessly and hit just the right sequence of jumps on the straight-aways, but if an opponent gets a lucky string of items or sets one off while you're in mid air you can quickly lose what ever lead you may have had. I'd like to see more focus on the skill based items and timing rather than heavy hitters that can't fail.
Never the less, still a worthy purchase.
